Retail Density and Marketing Policy Impact Map¶
Specification¶
The full specification below is extracted from Chapter 12: Substance Policy and Law.
Type: map
**sim-id:** retail-density-marketing-policy-map<br/>
**Library:** Leaflet<br/>
**Status:** Specified
Bloom Taxonomy: Analyze<br/>
Bloom Taxonomy Verb: compare
Learning objective: Compare hypothetical neighborhoods with differing
retail outlet density and marketing exposure to analyze how availability
policy correlates with community-level substance use risk.
Geographic scope: Stylized single-city map with four illustrative
neighborhoods (not a real city; labeled Neighborhood A-D for instructional
comparison)
Locations:
- Neighborhood A: low outlet density, strict local marketing ordinance
(green marker cluster)
- Neighborhood B: moderate outlet density, standard state marketing rules
(yellow marker cluster)
- Neighborhood C: high outlet density near a school zone, standard state
marketing rules (orange marker cluster)
- Neighborhood D: high outlet density, weak local enforcement of marketing
placement rules (red marker cluster)
Data represented: Number of alcohol/tobacco retail outlets per square mile,
distance from nearest school, and a marketing-exposure index (illustrative
0-10 scale) for each neighborhood
Legend:
- Marker color indicates overall risk profile (green = lower, red = higher)
- Marker size scaled to number of outlets
Interactive features:
- Click a neighborhood marker cluster to open an infobox showing outlet
density, school distance, and marketing-exposure index with a one-sentence
policy explanation
- Toggle layer: show/hide school-zone buffer rings
- Compare mode: select two neighborhoods to see a side-by-side infobox
comparison
Color scheme: Green-yellow-orange-red risk gradient
Implementation: Leaflet.js with custom stylized (non-real-world) tile
overlay and GeoJSON markers
