MooGraph is an utility to produce interactive dynamical graphs from statistical data. Deliberately inspired to GapMinder, it represents the evolution of multivariate data in time by means of coloured bubbles of variable sizes on an (x,y) plot.
This PHP script allows You to plot bubble charts on Google Earth. Have Your data in a query, view, table with fields: folder, name, latitude, longitude, radius, color, additional data. Set the DB parameters in the config file, and enjoy the results.
