The Gchart4mw allows for visualizing data in wiki pages. To do so it provides a couple of additional tags for embedding different chart-types. Possible charts are

• lines
• bars
• and pie-charts

The charts are drawn by using the Google Chart API.

All data for visualization is provided in CSV-style.
