Hi<br><br>Kindly see this video , it is  very informative, and hopefully enjoyable and would be of interest to data people and designers.<br><br><a href="http://www.ted.com/talks/lang/eng/david_mccandless_the_beauty_of_data_visualization.html">http://www.ted.com/talks/lang/eng/david_mccandless_the_beauty_of_data_visualization.html</a><br>

<br>My posting though is not about the video but about finding software (on Linux / Ubuntu) to do stuff like in the presentation , <br><br>any ideas<br><br>thanks<br>ram<br>
