Then, you can add as many graphs as you want, thanks to `SVG.addGraph(NAME, COLOR);` where COLOR must be a valid CSS color.
And you can add points thanks to `SVG.addPoints(GRAPH_NAME, POINTS);`. Points is an array of point objects, which are of the type `{'x': ABSCISSA, 'y': ORDINATE, 'label': LABEL}`. LABEL is the text to display in the infobox when the mouse is over the point. You can use '%x' and '%y' in labels and they will be automatically replaced by the coordinates. You can also use `<sup>` and `<sub>` HTML tags. You can add another (optional) element `click` which must be a ffunction to bind to onclick event on this point.
