I had been following up on HTML5 for the last few months and Abhay’s XKE session a couple of days ago really helped better understand the scope and capabilities of HTML5 as a technology. But having worked with Flex for nearly three years and being familiar with what the Flash platform does offer, there was not much in HTML5 that got me really excited.
In fact I am going to stick my neck out and make a series of claims and eventually conclude that the benefits of choosing Adobe Flex today completely overshadow HTML5. Read the rest of this entry

As promised, releasing an Adobe Flex 3 component for Choropleth Map. The Choropleth Map component is an extension/implementation of my Map component released earlier.
What is a Choropleth Map?
A choropleth map (Greek χωρα + πληθαίν:, (“area/region” + “multiply”) is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income.
The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variable within a region. — Wikipedia
—
The component does just that. It plots a map and then applies a theme to the various regions of the map. Relevant data and legend information needs to be provided to the component. (See example attached below!)
The component also provides tooltips on specific regions and provides an “Active Legend” that lets you highlight and hide/unhide specific regions of the map based on the data and legend.
