Top 7 Incident Types Called into the San Francisco Police Department
Individual Categories
About these Visualizations
This stacked area chart visualization's purpose is to get an idea of what types of crimes comprise
most of San Francisco's crime. I limited the number of crime categories to seven
for the purpose of this area chart, as there were many categories from the data. In this chart
we notice that Larceny Theft is the main offense recorded by SFPD in 2018. This followed by Other
Miscellaneous, Assault, Non-Criminal, Malicious Mischief, Burglary, and Lost Property.
This is a stacked area chart where the date column, which was wrangled as the month of the incident,
is encoded as x position on a linear scale and the number of incidents (i.e., the count of all incident categories on a specified day)
is encoded on the y axis. The areas are differenciated by the incident categories column and
is limited to show only the top seven incident categories sorted by the count of incident categories.
Below the stacked area chart you will find individual area charts allowing you to probe the data.
Stacked area charts often make it difficult to imagine an area chart on its own, so the chart here
is intended to help with just that. From this chart we can notice that over time, assault report counts have risen
over 2018.
