There are currently lots of websites reporting air quality index but few of them can provide a direct sense of the how air quality condition changes with time and region. We tried to transform the isolated data into live feed.

We picked seven days' AQI data, from 11/16 to 11/22. Using an XML data input, the AQI index of five cities, which represented by the size of five pink circles, can be automatically displayed while the tab moving along timeline. The distinctions between AQI values of different cities and tendency along time series can be directly monitored.
