Need to develop a (1) D3.js flexible configurable graphing dashboard app / portal where you can (2) add a list of charts by (3) specifying each remote datasources URL and (4) getting back a JSON or XML result set that will be plotted. The result set will contain all required data for each graph. We like to add graphs by (5) selecting from a menu and (6) positioning them on GUI, and (6) specifying the datasource URL. The dashboard must be (7) responsive. Once all graphs are added, (8) you can freeze it and (9) save a config file (as xml or json) for later (9) recall (by reloading file). All data from graphs can also (10) be viewed as a grid. This will be the only the first phase of the project. Please bid for such flexible graph app.
