#Fun with web scraping and text to speech

Recently I discovered the OSX say command. This command is pretty funny to play around with. Open up a terminal and type the following command:

  say "I cant let you do that dave"

This is fun to play with but let's see if we can make it into something useful aswell. I'm also interested in the aussie shares market (www.asx.com.au) so let's see if we can make it read out something useful like the latest breaking news for some shares that we are interested in.

I've added random points to this map that animate through, enter(), update() and exit() data binding from d3js. This shows how to display points on a map directly from an array of latitude/longitude points: [[137, 80], [-80, 80] ...].

This map shows the Natural Earth Admin 0 - Countries shapefile at 50m resolution. Converted to TopoJSON, only 140K gzipped. Each country is identified by its ISO 3166-1 numeric code.
