I divided the map into two parts, states and counties, to show different gun death distribution. Besides, it also includes a packed bubble chart for large US county data, a stacked bar chart to show each state detailed information, and an interaction scatter plot showing male and female victims by clicking the state in the map: multiple interactions and more detailed information to make the visualization of the whitehat.
- Using county data to connect with stategundeath data to get each county gun death count.
- Using Gun death per 100,000 as a standard to completion in each state, county, and city.
- Due to some special domain in the US, which causes some of the miss of state abbreviations, connect with the state.csv to clean data.
- Using average to fill in the missed population and using the 'Unknown' to fill in some missed county names (because some county has been merged with other counties.)
