A Heatmap or Heat Map chart looks like a table, which cells colors
depend on the cell value. These charts are popular in biology, web and other analytics,
geography, etc. Tabular data transformation for time series data projects one-dimensional

Many organizations utilize 360-degree feedback (also known as

use a spider chart, which renders multiple axes with the same scale.
