Web Mapping and Storytelling

Imagine you are building a dashboard for a city's recycling program. 1. You add a Category Filter for 'Material Type' (Plastic, Glass, Paper). 2. You set an Attribute Filter where 'Collection_Rate' > 50%. 3. When the user clicks 'Plastic', the map instantly hides all other points, showing only high-performing plastic recycling centers.

To narrate a study on urban heat islands: 1. Start with a Cover Page featuring a high-impact thermal image of the city. 2. Use a Sidecar to explain the correlation between lack of tree canopy and high temperatures. 3. Program a Map Action button labeled 'See the Impact' that zooms the map to a specific neighborhood with 0% canopy cover.

You are mapping CO2 emissions for three cities. City A emits 100 units, City B emits 400 units, and City C emits 900 units. 1. If you set the radius for City A ($V=100$) to $5$ pixels. 2. For City B ($V=400$), the radius is $5 \\times \\sqrt{\\frac{400}{100}} = 5 \\times 2 = 10$ pixels. 3. For City C ($V=900$), the radius is $5 \\times \\sqrt{\\frac{900}{100}} = 5 \\times 3 = 15$ pixels. Note that while the value increased 9x, the radius only increased 3x to keep the area proportional.
