Graph Generator
This is a simple form that generates a some barcharts and piecharts using random colors. Legend is the name of the item and data is the value assigned to it. Pretty basic stuff. You can only have 10 data items - sorry, the space in the graphs messes up if you go beyond that. Well, the space in the bar chart graphs messes up. The pie charts are fine to have more items and I do that on some of the statistics pages on this site.
The graphs are not the best, just simple coding in PHP using the GD extension. Numbers have to be positive and the form should restrict to two decimal places.
