This map visualizes U.S. population density by census tract using a choropleth coloring scheme, with darker reds indicating higher people per square mile. It renders static SVG via an HTML image tag, and the map is derived from 2014 American Community Survey data joined with census tract boundaries. The build uses TopoJSON CLI tools (`geo2topo`, `topomerge`, `toposimplify`) and D3 projections (`d3.geoAlbersUsa`), with color bins defined by `d3.schemeOrRd` and a custom legend.

Population Choropleth

A population choropleth of U.S. counties uses a logarithmic color scale to show population density, ranging from pale yellow to dark blue. The map projects counties with d3.geo.albersUsa() and renders them as SVG paths via d3.geo.path. Density is calculated by dividing each county’s population (from the 2010 Census shapefile, converted to TopoJSON) by its projected area, with the color domain set between the 1st and 99th percentiles. The topojson.feature API extracts county geometries for display.

California Population Density

This map visualizes population density across California census tracts, coloring each tract according to its population per square mile. It uses a threshold color scale (d3.scaleThreshold) with a sequential color scheme, and renders the state's county boundaries as an overlay. The visualization is built with d3.geoPath for map projections and topojson for handling the topology data. The underlying data comes from the American Community Survey’s 2014 5-year estimates, joined with Census Bureau tract shapefiles and processed through the command-line tools geo2topo, toposimplify, and topomerge to compute densities and simplify the geometry.

New York Population Density

A choropleth map of New York State census tracts displays population density, with a color scale ranging from light orange to dark red. Each tract's density is computed by dividing its population, sourced from the ACS_12_5YR_B01003_with_ann.csv file, by its area. The visualization uses d3.geo.path() to render the SVG paths from TopoJSON data, and d3.nest() groups tracts by color for efficient rendering. The map is projected using a custom Mercator projection centered on the state.

Untitled

This visualization displays population density per square mile across U.S. census block groups using a choropleth map. A threshold color scale with d3.schemeOrRd maps density values to sequential red tones, while a legend with a sqrt scale and axis shows the breakpoints. The code loads TopoJSON data via d3.json, renders block group polygons with d3.geoPath, and overlays county boundaries as black outlines. An interactive legend is constructed with rect elements and d3.axisBottom.

Untitled

A choropleth map of population density per square mile colors U.S. census block groups using a threshold scale and the sequential color scheme `d3.schemeOrRd[9]`. The visualization includes a square-root-scaled legend with an axis, and overlays county boundaries as black strokes at 30% opacity. The code loads TopoJSON data via `d3.json`, converts it with `topojson.feature`, and renders it with `d3.geoPath`. The legend uses `d3.scaleThreshold` and `d3.axisBottom`. The map is built with D3 v4 and React in the supporting files.

class 12

This choropleth map displays population density for census tracts in Maryland, using a color scale from `d3.scaleThreshold` and the `d3.schemeOrRd` palette. It shows how tract density varies across the state, with darker reds indicating higher densities. The visualization loads GeoJSON and population data via `d3.json` and `d3.queue`, then projects the tracts using `d3.geoConicConformal` and renders them as SVG paths with `d3.geoPath`. Density is calculated by joining population counts with tract land area from the GeoJSON properties.

Merged Choropleth

This choropleth map visualizes population density across California census tracts, using the 2014 American Community Survey 5-Year Estimate. The map merges adjacent tracts with similar density into single polygons, reducing the file size from 1.5M to 328K and improving rendering speed and visual clarity. The d3.geoPath renders the projected shapes, while d3.scaleThreshold and d3.schemeOrRd assign colors, and d3.scaleSqrt positions the legend. The code uses topomerge and toposimplify from the topojson library to consolidate boundaries, with county borders overlaid as an outline.

California Population Density II

A choropleth map of California displays population density per square mile across 23,198 block groups, using a sequential red color scale and a square-root axis legend. Drawn with `d3.geoPath` and SVG, the visualization loads topology from a preprocessed `topo.json` file, created by scripts that download Census block group boundaries and ACS population data via the Census API. The `prepublish` script projects, joins, and simplifies the data using `geo2topo`, `topomerge`, and `topoquantize`. County borders are overlaid as semi-transparent outlines.
