Green Button Grapher parses and charts Green Button Data.
First, download your Green Button Data from your power utility company's website. For example, here are instructions for downloading Green Button Data from PG&E.
Next, visit the hosted version of Green Button Grapher on GitHub and upload your Green Button file. Your data will then be displayed as a chart. Note that the file is only parsed by your web browser and not sent to a server.
