Study Radial Treemaps and create your personal with Python
The Treemap Idea
The “Treemap” was launched by Ben Shneiderman on the College of Maryland within the early 1990s¹. Merely put, it’s an environment friendly method of displaying hierarchical information as a set of nested rectangles. Though the idea is easy, the association of the rectangles is topic to an aesthetic desire, and varied association algorithms have been developed to reinforce the looks of the ultimate format.
Treemap Mechanics
Given a hierarchy, a Treemap represents every department within the hierarchy as a rectangle, which is then tiled with smaller rectangles representing sub-branches. The house in a Treemap is split in response to a particular attribute of the information (typically measurement or worth), and every rectangle’s space corresponds to the attribute’s magnitude, making it simple to match totally different elements of the hierarchy.
To account for the association of the rectangles, listed below are a few of the frequent algorithms that govern a Treemap’s building and supreme look:
- Squarified Treemaps² – creates rectangles as near squares as attainable by adjusting the side ratio of the rectangles
- Strip Treemaps³ – lays out the rectangles in strips, both horizontally or vertically, primarily based on the information’s hierarchy
- Slice-and-Dice⁴ – alternates between horizontal and vertical divisions which is easy however can create elongated rectangles
Treemap Options
- Proportions – the dimensions of every rectangle is proportional to the information level it represents, permitting fast identification of bigger and smaller objects
- Traces and Colours – intelligent utilization of borders, border measurement and shade, and buffers can delineate hierarchy ranges whereas container colours are sometimes used to characterize totally different dimensions of the information
- Spatial Effectivity – Treemaps…
