Pieroxy queries: "I recently had a look at various ways to draw a graph (lines, bar chart, pie chart...) for a web-based enterprise application. As we need some interactivity, the GIF image generated on the server-side is not an option. Here is the list of technologies I can think of: Flash is probably over kill and a closed technology. Java is very flexible but slow (to start and run). SVG (discussed here) still requires a plugin. VML is supported only on IE5+, but it is natively supported. Which one of these technologies is the more flexible and interactive? Is it reasonable to require a plugin from the end users of our enterprise application? Is IE5+ a wide enough target for an enterprise application?"
