A chart is a tool that allows you to present numeric data in a graphical view. Charts can be interactive and published in a web page.
The Charts' service is based on the FusionCharts software tool.
FusionCharts is a collection of chart types (line, area, bar, column, pie, donut, combination...) that can be used to render data-driven & animated charts in a web page.
FusionCharts converts numeric data to interactive visuals.
This is a central service; you do not have to install the files on your website to use it. The required files to run this service are hosted on both domains http://ec.europa.eu and http://europa.eu/ under the same directory structure.
