By default this will simply walk the graph, ignore epics and subtasks, and build everything into an SVG, which will be diplayed on the page.
4444
The resulting SVG can be copied from dev tools. I might later add another button that puts the SVG into an `<img>` tag so it can simply be copied with a context click.

Kiosk mode can be started via the Kiosk mode button. This will hide the form and periodically reload the page with the same options. Default period is 1 minute. Refresh the page to immediately refresh the graph.
