Visual Field Example 4 - SF Police Crime Data 2018 to Present (by category). Drilldown Charts with Map (mini-app)
The source data this example is based upon
Key aspects this example demonstrates
- Fetching a CSV dataset with a defined Cache Max-Age set to 3600 seconds (meaning the dataset won't be subsequently downloaded until 1 hour elapses)
- Creation of both a Custom Function to URI encode drilldown links and a database view to group by incident category
- Creation of a Bar Chart Visualization of Incidents by Category with drilldown links on the chart elements
- Creation of a second sequencing Pie Chart Visualization based on the passed Query String parameters from the Bar Chart drilldown
- Creation of another Custom Function to URI encode drilldown links and a database view to group by incident sub categories
- Creation of a third sequencing Map Visualization based on the passed Query String parameters from the Pie Chart drilldown
- Navigating of history between app "pages" should function correctly (ie, back history)
- Once the initial data is loaded, this entire mini-app can function offline (if loaded over a https:// protocol context)
