Google has officially released their Official Trendalyzer Gadget, which mashes their chart API with Trendalyzer’s statistic tools.

Ruport is a Ruby reporting library that can hook into ActiveRecord, CSV, or SQL/DBI. It has a simple formatting language, can produce PDFs and graphs, and even does some code generation to make things easy.

A Ruby on Rails diagram generator. Now you can see your ROR projects in full unidirected beauty. Graphs are produced in SVG and PNG using Graphviz.

MX Graph, uni-directed graphs in Javascript. I don’t recommend this library specifically, but expect good things in appication land from Javascript thingies. (Note the use of “thingies” is in retaliation of language like “leveraging”, as found on the MX Graph site).

An example of animated directed graphs in Javascript. A bit CPU-hungry, but an example of what can be done.

How to Make Great Photographs. Art has very little to do with your equipment–it’s an expression thing.

CSS Bar Graphs. An interesting use of CSS.
