Chad Norwood Google Calendar Map

This is an open source project that I would like to alter. It currently pulls data from Google calendar events to plot pin drops and data to a map. I would like to instead have it pull from an external json file.

The Chad Norwood project and source can be found online. The raw json data I want my project to use I will make available.

PLEASE REVIEW CHAD NORWOOD project before responding to this post.

Thanks ! lol
