Format parliament diagram

How to use this script:

  • Type the title of your graph (e.g. "Blueland Senate 2093") in the box marked "graph title"
  • Type the list of parties in the box marked "List of parties". Each party must have a name and a number of seats (can be 0), and if you like you can also add a colour. The parties in the list must be separated by semicolons (";") and the party information must be separated by commas (",") (For example, if you type: "Party A, 33; Party B, 22, #99FF99" you will have two parties, one labeled "Party A" with 33 seats and a random colour, and one labeled "Party B" in light green.)
  • The hight of the diagram (in blocks) is chosen automatically, but if you need to change this, you can set it by hand by typing a number in the box marked "Height of diagram in blocks"
  • The script will give the code of the svg diagram when you press "send". You can cut and paste the code into a text editor and either edit it or upload it onto Wikipedia.
