Contributions Calendar
This extension for WYSIWYG Web Builder is a based on contributions-calendar.js, a third party Javascript library (https://github.com/bohdaq/contributions-calendar) that generates heat maps to visualize date-based activity and trends.
It uses color shading in calendar blocks to indicate intensity – lighter colors for less activity, darker colors for more.
The extension can load data from MySQL, CSV, MS Access (MDB) or JSON.
