Description

This workflow is a replication of the analysis from an OSCon 2004 presentation by Megan Conklin, entitled "Do the Rich Get Richer?" to demonstrate scale-free distribution of FLOSS developers among projects.

The workflow retrieves the current number of active developers (for the most recent calculation of said statistic) from the FLOSSmole database. It summarizes and plots the distribution of developers to projects, on both a straight and log-log scale. It also generates a flat list of the developer counts for visualization in other software.
