Enterprise adoption: Does HTML5 stand a chance against Flash technologies?

10 Comments »

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 »

Choropleth Map Component (Adobe Flex 3)

15 Comments »

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.

choropleth-map-example What is a Choro­pleth Map?
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.

Map Component (Adobe Flex 3)

6 Comments »

map-exampleReleas­ing a sim­ple, pow­er­ful and exten­si­ble Map com­po­nent devel­oped using Action­Script and Flex 3. The idea is that a map con­tains one or more poly­gons rep­re­sent­ing each sub-region. Each poly­gon can have mouse events attached to it and can have fur­ther prop­er­ties set. This con­cept is fur­ther extended in my sec­ond map com­po­nent i.e. the Choro­pleth Map that will be released later this week so stay tuned!
