Grafico – Charting Library Built with Raphaël and Prototype
This means you get awesome graphs such as stacked area charts and sparklines, but no pie charts or bar charts with every bar a different color. Each graph type has numerous API options to customize it’s look and behavior. Some highlights: pop-up hovers, meanlines and watermarks. Minified, Grafico is about 30kb and available under the MIT license.
Requirements: Raphaël and Prototype.js
