We're currently working with a dozen different clients, all web application (re)designs. All of these clients have data rich applications and need equally rich data visualizations to help their end customers analyze data quickly and effectively. What makes my job really interesting is that these clients are in different industries and are using different technologies. So we have pulled together a set of 28 tools for creating graphs, Gantt charts, diagrammers, calendars/schedulers, gauges, mapping, pivot tables, OLAP cubes, and sparklines, in Flash, Flex, Ajax or Silverlight.
