A visualization constructed using the vega-lite-api.

Realized my first sketch. While realizing this visualization, I find it out that "TimeUnit" in vegalite API is defined as "temporal" field. That took me a lot of time to got understood.

By this visualization, we can tell that police shootings keep at a level and never go down. Besides, white victims accounted for the largest number of the shootings all time.

The data shown here comes from the US Police Shootings.
