A visualization constructed using the vega-lite-api.

The data shown here comes from the Bangkok Smart Monitoring System. The line charts represents the number of new HIV cases aggregated by district (in Bangkok).

Development: Users can choose which districts they want for the graph. It still has a bug where the render delay 1 step (will figure it out why). Also, in the future, the plan is to use Stylished Dropdown Menu that interact with user better.
