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 category.

Direct upload functionality in beta test

You can now directly upload arch-style diagrams to Wikimedia commons with this new interface. Please submit bug reports and feature requests at the project's issue tracker.
