Data visualization helps people to understand huge amounts of data in easily digestible visuals. Charts are usually the simplest way to present the information. Here we just give a short update on the charting possibilities in TotalSheets. The users will be able to use different 3rd party javascript/jquery chart libraries in their online spreadsheets. As the core libraries we will be using RGraph and jQuery Sparklines.
For a start see the screenshots for Bar, Horizontal Bar, Line, Combined, Pie and Donut charts created with RGraph library (other to follow).
Let us know your opinion which chart library would be most in demand for your purposes.
