IPU-Chart SVG Chart Library

IPU-Chart is a powerful, easy to use SVG chart library available for EPUB3, WordPress and other HTML based publishing systems. It supports currently (horizontal and vertical) bar chartspie charts, donut chartsline charts, scatter charts, animated, multi-series bubble charts and world map charts.

Other chart types like stacked- and grouped bar charts, multi-series line charts, area charts and other types of (geographical-)map based charts will be released in short time.

IPU-Chart allows you to load the data to display as a chart from a remote service that delivers csv (comma separated), tsv (tab separated) or json (javascript object notation) formatted data. Alternatively you can export the data from your favorite spreadsheet application (Excel, Numbers, Open Office) and display it in your pages as a chart.

IPU-Chart can be used directly in your HTML-pages, as shortcode in WordPress and in EPUB3 based eBooks. Here an example of a bar chart created with IPU-Chart. Move the mouse over a bar (or tap on a touch device like iPhone or iPad) to see further details.
