Documentation:

• Line 1 is HTML element that the widget will be inserted into.
• Next is a self-contained JavaScript function that gets called immediately. On line 11 we're passing the function the strings, 'ideamarketplace' and 'info_id'. 'ideamarketplace' is the id of the HTML element that we're inserting the widget into which matches the ID on line 1. info_id is whatever value they want to show up in the CSV report. Maybe they change that for different widgets, or maybe the page itself has a value that they'd want to pass into the info field.
• Line 5 has widget attributes (colors, etc.) that may be modified.
• Lines 6 and 7 may be modified to suit the user.
