An iframe is a way to load external content into a website. Specify the width, height, and the source of the externsl content and put the tag in your content just like you
would any other. I added the broder style to each of the tags because the default border looks garbagio, but let me know if you want something even cooler (drop shadow, dashed line border, etc.).
Just copy/paste the tags below for linechart and barchart
NOTE - the urls are not finalized, I'll let you know when they are
