The UK Government and Parliament Petition website provides the British public with the ability to obtain government responses on issues they care about. All petitions that surpass 10,000 signatures receive a government response, whilst those that surpass 100,000 signatures are considered for debate in Parliament.
The government has made all petition data available through an API. I have used this API in a React app to provide a more dynamic petition search experience, including the ability to view PlotlyJS graphs and LeafletJS maps of signature count data.
