Start with "Why?" A good visualization is always a combination of the right tools and a clearly formulated goal. Therefore, in any case, you need to start with the question "What task does my visualization solve?". The answer should be described in one or two sentences. Additional questions can be: "What should the user learn from the results of the review?", "What information is most important to convey?" If you have decided on the goal, then you can proceed to production. The visualization construction algorithm Visualization is about dynamics and differences, so first of all you should decide what variables you have. For example, I want to compare three students - Oleksiy, Mykhailo and Pavel - and their test results. In this case, my variables are the names of the students and their grades.
When it became clear with the variables, it is worth understanding what type of data these variables refer to. The types of data are: quantitative - everything that can be counted: qualitatively ordered, for example, days of the week or months; qualitative Norway Phone Number unordered, for example, the names of the countries of the Olympiad participants, names, etc. At this stage, we can already make the simplest table that will organize our task. Student Rating Alexei 3 Mykhailo 5 Paul 6 The next stage is the selection of the correct visual elements that will be able to convey information. Visual elements are divided into two types: Labels: point, line, plane (2D), sphere and cube (3D). Channels: position, size, orientation, color scheme (hue, saturation, brightness), etc. I think you have understood the point.
Now our table needs to be reformatted - we should decide what type of data each variable has and what visual elements are best to represent it. Changeable Data type Visual channels Name of the student Qualitative Orientation, color, shape Rating Orderly Size, orientation, position Well, let's choose a form to display the name, and just a value to display the rating. It does not seem very clear, or rather, very unclear. Let's try another way - let's take the color for the student, and the size for the assessment. It's better: and it's clear that the purple color is the best, but you can't do without a legend. So let's try again. We choose a position on the plane as a visual channel for both the name (by X) and the rating (by Y). It already looks pretty good. But I personally prefer the option with Y orientation of the name, and scores on X (inversion of the previous graph) Let's summarize the algorithm: Decide on the composition and number of variables.
