This is a tool to generate arch-shaped parliament diagrams.
To use this tool, fill in the name and support of each party in the legislature, clicking "add party" whenever you need to add a new party.
Then click "Make my diagram", and a link will appear to your SVG diagram. You can then freely download and use the diagram.
To use the diagram in Wikipedia, I recommend uploading it to Wikimedia Commons.
If you do upload it, I recommend adding it to the election apportionment diagrams
Direct upload functionality in beta test
You can now directly upload arch-style diagrams to Wikimedia commons with this new interface
