A new version of air quality map for the Luftdaten. You can find a here a Live Version.

Goals and ideas

  • visualise recent sensor data on a map
  • switch between sensor data (PM2.5, PM10, humidity data, ...)
  • visualization between Air Quality Index (AQI) and normal default levels
  • identify and add existing air quality data from external sources

  • d3 (visualisation framework)
  • webpack is used for deployment
