Contour map

This chart displays contour maps.  Given two-dimensional coordinates and data on the values corresponding to each point, different values can be expressed in different colors.
In the sample script, the number of color divisions can be increased for a more detailed look at value changes, or values below a certain level can be omitted, allowing each user to choose his or her own expression method. Not only geographical expressions such as contour maps, but also physical indicators such as temperature and pressure distribution can be visualized.
