“Bubble”-plot is a different way to present your data, this kind of plotting broaden the possibilities of representation beyond the classics histograms and pie charts.

The program is based in a open-source script which has been modified to be able to add other features, for example values in percentage ,the feature’s unit of measure or optimal adaptation of the on-screen display.

The script’s input is a flat-file (CSV), where the first column is the “name” column, the second is the “value” column, and optionally a “color” column may be added.
