pi-chart

A basic server to display basic 2D Raster/Vector content on the Raspberry Pi via HTTP. This is intended to be used to display graphs and charts on a TV as a basic kiosk/heads-up sort of display.

To current TODO list/some ideas:

• Get HTTP server listening for POST requests.
• Allow Images to be POSTed directly.
• Allow Image URLs to be POSTed.
• Create a JSON or XML-based format for sending raw data to be graphed:
  • Bar
  • Line
  • Pie
  • Points (Scatter)
  • Others?
  • Images
• Allow multiple content pieces to be put together in a single POST and displayed in different parts of the screen.
• Create an update-only mode where layout and display is set, but datasets change dynamically.
