This example displays a choropleth-style map of California zip codes, with each region colored light blue and highlighted red on hover. The visualization renders stroke mortality counts for 2016 by overlaying zip code boundaries from a GeoJSON file onto a Mercator projection. The code uses D3 v5’s `geoMercator`, `geoPath`, and `zoom` to create an interactive, pannable SVG map, while stroke data from a CSV file is joined to the geographic features via zip code identifiers.

CA Zip Code Map Part 2B

This example maps California zip code boundaries, coloring each region light blue with a red hover highlight. It visualizes stroke mortality data by zip code, though the chart itself displays the geographic shapes without encoding the count values in the fill. The map uses a Mercator projection with d3.geoPath and d3.geoMercator, rendering SVG paths from a GeoJSON file of California zip codes. The stroke data is loaded from a CSV, and the map supports pan-and-zoom interaction through d3.zoom.

CA Zip Code Map Part 2E

A choropleth map of California zip codes displays stroke mortality counts for 2016, with each zip code polygon filled in red. The visualization uses d3.geoMercator and d3.geoPath to project and render GeoJSON zip code boundaries, while d3.csv loads the stroke data joined to the map features. The SVG map supports d3.zoom for panning and zooming, and hover effects highlight individual zip codes.

CA Zip Code Map Part 2E

A choropleth map of California zip codes shaded by stroke mortality counts from CSV data. The visualization uses D3 v5 with `geoMercator` projection and `geoPath` to render SVG paths, while `scaleOrdinal` with `schemeSpectral` assigns colors based on death counts. Hovering highlights individual zip codes in red, and a zoom behavior enables interactive panning and scaling of the map.

CA Zip Code Map Part 2B.1

This example maps California zip code boundaries and overlays stroke mortality data from a CSV file. Each zip code polygon is rendered using `d3.geoPath` with a Mercator projection, and hover effects highlight individual regions. The visualization supports pan and zoom interactions through the `d3.zoom` API. The GeoJSON data comes from an external GitHub repository, and the stroke counts are joined to the map by zip code, though the counts themselves are not visually encoded.

CA Zip Code Map Part 2C

This map of California zip codes visualizes stroke mortality data from a CSV file, with each zip code area represented as a selectable polygon. The visualization uses a Mercator projection and D3’s geoPath to render the GeoJSON boundaries, while a zip code identifier appears as a tooltip when hovering over each region. Built with d3.v5, the map supports zooming and panning via d3.zoom, and employs event listeners to handle user interactions. The stroke counts are not visually encoded by color, but the data is accessible through the interactive tooltip.

CA Zip Code Map Part 2C

This map displays California zip codes with stroke fatality counts from 2016, using a Mercator projection. Hovering over a zip code highlights it in red, while tooltips reveal the count for each region. The visualization uses d3.geoMercator, d3.geoPath, and d3.zoom to render and navigate the geographic data. Zip code boundaries come from a GeoJSON file, joined with CSV data containing stroke counts, and the SVG is rendered with D3 v5.

CA Zip Code Map part III

This map displays California zip code boundaries colored green, with stroke mortality counts from 2016 stored in a CSV file. The visualization uses D3 v5’s `geoMercator` projection and `geoPath` to render GeoJSON zip code polygons as SVG paths, while `d3.zoom` enables pan and zoom interactions. Hovering highlights regions in red, though the code does not yet bind the CSV count data to the map shapes.

CA Zip Code Map Part 2D

This visualization displays the number of stroke-related deaths per California ZIP code for 2016, using a choropleth-style map where each ZIP code area is rendered as a red SVG path. The map is projected using a Mercator projection centered on California, and users can zoom and pan the view. The code loads geographic boundaries from a public GeoJSON repository and joins them with mortality counts from a local CSV file using d3.csv and d3.json. Interactive zooming is handled through D3's zoom event, while d3.geoPath generates the map shapes.
