I may need to display live graphs in a browser, i.e. ones that are regularly updating based on information received from a back-end data source of some type. The updated data could probably be made available in any form desired, such as database table data, an XML feed, or perhaps even newly generated grapics for the graph being constantly refreshed.
Does anyone have any suggestions for how to best do this? Options that occur to me include Java applets, something done with Flash, and repeatedly generated graphics from the back end, as mentioned above. (Though I would expect the graphics solution would be too expensive in terms of bandwidth.)
Any advice? I’m interested in advice both on the display technology for the front end, and the communications technology to use between it and the back end. Thanks.
