visualization

Visualize is a Views style plug-in for implementing the jQuery Visualize charting tool.

jQuery Visualize provides accessible charts providing textual information to non-visual users.
It uses a technique with JavaScript to scrape data from an HTML table and generate charts using the HTML 5 Canvas element.

Hey, I've set up a data pipe from Drupal to Flex/Flare using jQuery. Its as easy as this:

1. IN DRUPAL TEMPLATE.PHP
   function phptemplate_views_view_list_{viewname}($view, $nodes, $type) {
   foreach ($nodes as $i => $nid) {
   $node = node_load($nid->nid);
   $output[]= json_encode($node);
   }
   return 'var videos=['.implode(',',$output).']';
   }

2. IN THE HTML-TEMPLATE

<

script type="text/javascript">
function getData(){
$.getScript("http://example.com/view", function(){
/*$(videos).each(function(i){

Just stumbled upon this post on Mashable: http://mashable.com/2007/05/15/16-awesome-data-visualization-tools/

Several good ideas what could be implemented in Drupal on the field of visualization. With open formats like SVG there is no stopping us :)

with lots of graphs - I would like to know which graphing library you are planning to use and how you think you will interface it.

Currently my problem is to find a good algorithm to visualize a tree. The problem is:

• determine each point's coordinates - find a layout
• draw the layout

This tree is not weighted, directed one - breadth-first search output for example. The second point is very obvious. The first one is not easy, especially for very big trees (~3000 points)
