RE: Graphing sensor reading

Hi guys, so I was seeking some advice. I am presently working on an interactive handle that uses flexi force sensors to measure the amount of pressure a user puts throughout the process of getting up, using the aforementioned handle for assistance. Accordingly leds alert the user weather or not they've put a sufficient amount of effort into the action or not. However, although I've sorted out the mechanical portion of the piece I was wondering how best graph the data visually? Especially on a website. I need to create some sort of graph tht updates live on a website. I was considering flash or processing but I don't know if any of the above will render dynamically? Does anyone have any suggestions that would be quick and easy to integrate? XD Thanks!
