In this example we show how it is possible to directly retrieve files that are on a github public repository. 

 

First we retrieve a JSON containing all the demo files present in a directory and in a second step we retrieve the file and display it in a 'display Value' module using the 'chart' type rederer.

 

The only problem is that the value returned by github contains the properties type and url that is incompatible with the visualizer and therefore we need either to delete or remove url.
