Most notable evolutions:

• you can now create bubble charts - they are still a bit primitive, but that's a start;
• you can now edit, correct, modify any graph: on the page of the graph, bottom right, there is button for "edit"
• better presentation: many graphs are automatically centered, display bugs were corrected, etc.
• the syntax to type in the description of graphs is now inspired by wiki instead of being pure html, this is more intuitive

Feel free to create as many graphs as you want !
