Looking for rich SVG Charts that refresh themselves via AJAX ? GerbilCharts is a SVG based charting library designed for plotting timeseries data like network traffic.
GerbilCharts allow you to easily create interactive and powerful charts for use as standalone or in a Rails application.
GerbilCharts uses stylesheets to customize appearances of almost all visual
elements (colors, fonts, line strokes, fills). You can use the supplied
stylesheet (eg, brushmetal.css) or derive your own from it.
GerbilCharts searches for stylesheets in the working directory and the public directory of the gerbilcharts gem.
Here are some key features of "GerbilCharts":
· Models to help manipulate timeseries data
· Many chart types (line, area, bar, stacked area, impulse) – more coming !
· Customize via stylesheets instead of calls to setFont, setLineStyle, setColor etc
· Interactive : Tooltips, handle clicks on chart objects
· Ajax updates : gerbil.js allows each chart to autoupdate itself with new SVG elements.
