Create HTML5 code based on a simple Flash model

The aim of the project is to create HTML5 embeddable code with the same features and behavior shown in the Flash object on [login to view URL] The code should take the following data as easily loadable inputs (preferably from a restful web service): (1) a jpg image for the background, (2) a set of points with coordinates (x,y) that will lie on the "upper border" of the chart, and (3) a vector of asset weights (containing names and weights for "n" assets) for each point of [2]. The user should be able to navigate through the points using the mouse, and when the pointer is over any point from [2], information for the top-3 weights of the vector should be presented on a floating area.
