This is a tool to generate Westminster-style parliament diagrams, with a house composed of a left bench, a right bench, a cross-bench group and a "head" - for example Speaker of Parliament.
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 it in Wikipedia, I recommend uploading it to Wikimedia Commons. However, please make sure that you confirm with other editors what the consensus is on which layout and settings to use. If you do upload it, I recommend adding it to the election apportionment diagrams category.
