Google Chart Tools

So, I have been using the Highcharts JavaScript API to draw the income charts on this site. I spent a lot of time figuring them out and I really really liked how the high-charts looked on my site. However, the free version just did not offer very good ways to display really dense data sets. My experiment has been going on long enough that the charts were getting unreadable and cluttered and so I went searching for free alternative charting API that had scroll bars and could better handle dense data. I found out about Google Chart Tools and really liked them. They are the charts you can currently find on my site are the ones documented here. It did take me several hours to figure everything out but all in all I highly recommend them if you are looking for a free charting API and need to display dense data.
