What do you understand by Data Visualization?
A graphical representation of data and information is known as Data Visualization. In this, visual elements, such as graphs, charts, and maps, are used to offer an easy and accessible way of understanding and analyzing trends, patterns, and outliners in the data. On the whole, data visualization and data science are not two distinct entities. They are both bound together and are complementary to each other. In short, Data Visualization is nothing but a subset of Data Science.
How to pick the best visualization tools for data science?
Many a time, organizations run into challenges, which relate to relevant communication. If the organizations have the best visualization tools for data science, they can overcome any such challenge. These best data science visualization tools are incredibly helpful and help overcome all plausible situations of under communication, bad communication, or miscommunication.
Now, how can you pick the right and the best data visualization tool? There are a bunch of factors, which are involved in picking the right data science visualization tools.
- Firstly, you need to start by identifying the needs of your organization.
- This is important because it will help you in the second step, wherein you’ll compare the needs of your organization with the capabilities of the different data science visualization tools.
- After you have worked this out, it would be easier for you to find the desired solution, i.e., the best visualization tool for data science for your organization. It would also make it easier for you to proceed further.
It is important to understand that just like any other tool selection, in data visualization, too, there’s not one tool, which will be perfect for all organizations. However, to find the best visualization tool for data science, you need to take out a moment and answer a few questions. Here are some questions which you have to consider:
Step 1: What are the different questions, which your users are asking?
Now, let’s start with the basics – why do you want the best data visualization tool? Is it your technique to find ongoing trends? Do you wish to use it to satiate the operational reporting needs of the business? Many times, businesses don’t even know the reason why they are using visualization tools.
The primary categories, which distinguish between these questions are:
Now, if you wish to put forth the comparison over time, you’ll use line charts, area charts, or column charts.
More specifically, if you wish to put forth an evolution, you should use a vertical column chart, as, in it, the time can be expressed from left to right. So, in this case, horizontals wouldn’t do you any good.
Similarly, if you have to compare different items, then you can use a bar chart, table, or spider chart.
Stacked column charts or stacked area charts are ideal when you have to express the relationship of the part to the whole.
Step 2: Identify the Objective
Now, before you start with the visualization process, do ensure that the objective of this visualization is known to you. It will make it easier for you to determine how many dimensions or values you need. This, in turn, will give you a better direction in choosing the best data science visualization tool. Further, it works best when you try to comprehend what the users wish to see.
Step 3: Tailor the tool choices according to needs of the audience
The primary skill for any data scientist is the ability to communicate the results in a manner that they are easily understood by the stakeholders. Since the data projects are collaborative across different functions and the results of the data science are usually incorporated in a larger project, the real impact of the work of the data scientist primarily depends on how well others can comprehend the insights to take the following actions.
Step 4: Pick tools, which minimize visual bloat and maximize clarity
Both in your writing, as well as in your day to day life, it helps to be aware of the cooperative communication principles by Grice. It involves the following:
- Maxim of quantity – At all times, we should be informative as much as is required. However, in no way should we speak more or less than what is required.
- Maxim of quality – As a speaker, we should always speak the truth or only put forth things, which can be proven by adequate evidence.
- Maxim of relation – The response that you give out should be relevant to what’s being asked.
- Maxim of manner – Do not ever be obscure or ambiguous. Whatever you say has to be clear and straightforward.
Step 5: Pick tools, which give more value to your data
Now, under this step, you have to pick the best visualization tools for data science, which helps you put forth the data in the most meaningful format. To accentuate the effectiveness of your communication, this step should certainly be on your mind with regards to the selection of the data science visualization tools as well as through the analysis process. You need to determine the communications format, which will be helpful for the audience to ensure that your communication inspires action and does not go in vain.
Is your audience going to physically carry with them a fact sheet or an executive summary whenever they move from one customer site to the next? Are they going to remove the chapter or pages from a report, which best relates to the research? See, the purpose of the entire information depicted by the best data visualization tools is to determine the format of the piece. Don’t forget we live in a distinctively visual age, and hence visualization tools for data science are important to give value to the data.
Step 6: Distinguish between exploratory graphics and presentation
The presentation graphics prepared by the best data visualization tools are much like the proofs of the theorems in mathematics. They do not give any clue on how this result was reached, but they do have to offer a convincing outlook as to how this conclusion was reached.
On the other hand, the explanatory data science visualization tools are to look for the outcomes. A bunch of these could be used, and at all times, they are supposed to be informative and fast and not precise or slow. These are not meant for presentation. Hence, you don’t have to put forth any lengthy captions or detailed legends.
Moreover, the primary difference between the presentation graphic and the exploratory graphic is that the former data science visualization tool will be drawn for viewing by thousands of different readers, while the latter data science visualization tool will be drawn complementary to the different data investigations of a single analyst.
Step 7: The form of the data visualization must follow its function
The visualization, which you create with your best data visualization tools, would depend on:
- The properties of the data
- The questions that you intend to ask
- How you would like to communicate and present the insights to the audience.
For instance, representing the growth in sales in each year would require a distinct data science visualization tool than depicting the connection between discounted items and the profits they fetch you. Hence, the knowledge of what you aspire to depict will determine the type of visualization tools for data science used by you.
Step 8: Try to strike a balance between the needs and the functionality
Now, the drill of determining the best visualization tools for data science would need a certain balance between the analyst needs and the proportionate technical requirements. It would help determine the requisite training schedules and examine whether or not you should add components to the current technical architecture to cater to all the business needs. At times, you’ll find that your stipulated needs tend to compete with each other or rather put forth contradictory ideas in the represented visualization tools for data science. These should be eliminated.
Step 9: Opt for best data visualization tools, which combine different data sources and factors nicely
Besides the trends over time, the metric values comprise distinct parts or components. For instance, revenue might be derived from different types of sales leads or various products. Being able to use the best data science visualization tools for the visualization of how the different pieces contribute to the absolute performance is the next vital step.
Step 10: Search for features, such as dynamic data and animation
When you are looking for the best visualization tools for data science, there are certain things that you need to be careful about. It is so because picking the right visualization tools for data science will help in achieving optimal functionality and deliver excellent ease of usage. Analysts from Forrester, Noel Yuhanna, and Boris Evelson recognized six distinct traits, which help in identifying advanced tools from the use of the simple static graphs. These traits comprise visual querying, dynamic data, animation, linked multidimensional visualization, actionable alerts, and personalization.
Step 11: Pick right colors for representation
In your used best data science visualization tools, it is important to be careful with the colors. The colors used in the best data science visualization tools should be indicative of whether something is important or not. It is believed that colors play an important role in attracting the attention of the user. For instance, you can use the “alarm colors” such as color red to represent a decline in the sales in your best data science visualization tools. Similarly, the color green can be used in the visualization tools for data science as a sign of the target achievement in the marketing campaign.
Step 12: Try to keep it as simple as possible
In the visualization tools for data science used by you, you should curtail yourself from depicting a lot of information in the single visualization. You would not want your user to keep searching for their answer. The answer to their question should be just right there. In case, you would want your user to be able to see more information than what is available up-front, you have to make a setting in your best visualization tools for data science, wherein, your user can click onto the drill-down function from where they can enable this.
