What Lebedev didn’t see, or Size, area and volume in diagrams
It is rarely brought to the humble programmer to catch themselves with what. Before us is a fresh "Business Lynch" .
Let's look at the two biggest cars, white and blue. It seems that white is 70 thousand, and blue is 40? In my opinion, no, about three to four times more.
Quickly redrawn four values. I can only draw elephantswith a hat in a boa, so I took a typewriter from OpenClipArt and propagated it in Inkscape.
')
In my opinion, the ratio of numbers worked out better. What I've done? I made the numbers proportional to the area of the machine (and the size is the square root of the number).
On school tables in history and geography, I met such diagrams - for comparing grain production, water reserves.
Yes, a large brick in size is larger than a small one. Is it only visible on a flat figure? Not. Hence the big rule.
In the diagrams, it is necessary to do so that the values are proportional to the shaded area. It is the area, not the linear dimensions or volume of a pseudo-three-dimensional figure. Here, for example, the correct infographics.
Corollary number one. Make a three-dimensional bubble diagram ( 3D bubbles ). Yes, the bubbles are three-dimensional, but their diameter must be equal to the square root of the number (and not the figure itself or the cube root). So this diagram is wrong.
And a consequence number two. Three-dimensional pie chart - in principle, lies, provocation and cheating. Here is a classic example from “Manipulative Diagramology” : compare A and B!
