datadensityplot

Shows the data density of a 2 dimensional distribution.

The problem of showing data density visually is not mathematically well defined, and there are several methods. The program uses sum of reciprocal squared distance to calculate density at each point, with a smear factor to prevent points going to infinity. The smear factor also controls the amount of clustering.

There are several options for colour output. Input is via a csv (comma-separated values) file.

Now there's a nice GUI built in Baby X for Linux and Windows
