This visualization maps the population density of US counties, with color intensity representing inhabitants per square kilometer. Built using R with the `tidyverse` and `sf` libraries, it downloads county boundaries from the US Census TIGER/Line shapefile and joins them with population estimates from the Census Bureau’s 2018 county data. The `st_area` function computes each county’s area, then divides total population by area to derive density values, resulting in a choropleth map displayed via geographic rendering.

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.

2010 Demographic Profile of US Counties

This visualization displays a detailed demographic profile of US counties from the 2010 Census. It uses a choropleth map rendered with the `d3.geoPath` and `d3.geoProjection` functions, with color encoding for population metrics. Interactive hover states reveal precise data values using `d3.select` and tooltip bindings from the `d3.brush` library. The dataset, sourced from the Census Bureau’s TIGER/Line files, includes age, gender, race, and Hispanic-origin breakdowns for each county.

U.S. Population Density

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.

US County Populations - D3 Visualization

This interactive choropleth map visualizes 2013 U.S. county population estimates, using a logarithmic color scale with a sequential interpolateGnBu scheme to encode values. The visualization binds population data from Wikipedia-sourced CSV files to county paths from the us-10m.v1.json TopoJSON, rendered with d3.geoPath using a null projection and geoTransform scaling for performance. It features zoom/pan capabilities via d3.zoom, hover tooltips, and toggleable county borders, with a legend provided through d3.scaleSequential.

Shared Data

This interactive map visualizes the population distribution of the United States by rendering state and county boundaries alongside state centroids. Built using D3.js, the visualization combines `d3.geoPath` to project and draw the geographic shapes from the included `us-states.json` and `us-counties.json` files, while `d3.geoPath` also handles the state centroids from `us-state-centroids.json`. The map is rendered dynamically, displaying the detailed boundaries and population data sourced from the provided gist.

NY Counties

This example visualizes population density across New York counties using a choropleth map with a threshold scale and the OrRd color scheme. Hovering over a county highlights it and displays a small pie chart comparing population, land area, and density. The visualization is rendered with SVG and uses d3.geoPath with a Transverse Mercator projection, along with topojson-client to process county boundaries and d3.queue to load population data from JSON files.

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

This choropleth map shows the population distribution across U.S. counties, with a color scale from light blue to red indicating population magnitude. The visualization is rendered as SVG using D3 v7, employing `d3.geoAlbersUsa` for projection and `d3.geoPath` to draw county boundaries from `counties.json`. Population data is loaded from `PopulationEstimates.csv` and matched to counties by name, with a tooltip showing county name and population on mouseover. The code uses a sequential color scale with an RGB interpolator.
