i need to develop a web application which shows a map, that displays a GPS Route. So far I can do this using Openlayers or ArcGIS Server.
Now I want to add an interactive graph below the map. In this graph I want to display for example "Speed" and on mouse-over on the Graph the corresponding location in the map should be displayed.
Does anyone know an existing library or can give me recommendations on which architecture to use? Or do I need to programm this thing from the ground up on my own?
