This choropleth map visualizes the estimated number of people in poverty per U.S. county for 2021, using a logarithmic color scale from white to dark orange. Hovering over a county reveals its exact poverty count via a tooltip. Built with D3 v5, the map uses `d3.geoPath` and `d3.scaleThreshold`, drawing county and state boundaries from topojson data, with a legend and color encoding derived from the `d3-scale-chromatic` scheme. The poverty data is loaded from a CSV containing FIPS codes and county-level values.

Choropleth map in D3 - Poverty Estimate

This choropleth map displays the estimated poverty rate for each US county in 2021, using a blue color scale to show the percentage of the population in poverty. The map is rendered as an SVG using d3.geoPath and topojson features, with state boundaries outlined in white. A legend and title are included, and the data, sourced from the USDA, is loaded from a CSV file and joined to the map using county IDs. The visualization uses D3 v5 and the topojson library for geographic data processing.

Choropleth Map of County Data

This choropleth map displays poverty rates across U.S. counties, with each county filled using a green sequential color scale from d3.scaleThreshold and d3.schemeGreens[5]. The visualization loads county boundaries from a TopoJSON file and joins them with CSV poverty data via d3.map, rendering the geographic features as SVG paths using d3.geoPath. A legend with a linear scale and axisBottom shows the poverty percentage range, while state borders are drawn as white strokes using topojson.mesh. Tooltips provide exact poverty percentages on hover.

Choropleth Map of County Data

This choropleth map visualizes county-level poverty rates across the United States. The map uses a green color scale, with darker shades indicating higher poverty percentages, and includes a legend with a color gradient. The visualization is rendered as an SVG and built with D3 v5, using `d3.geoPath` to draw county and state boundaries from a TopoJSON file. County data is loaded from a CSV and mapped to colors via `d3.scaleThreshold`, while tooltips display the exact poverty rate for each county.

D3 Choropleth Map

This D3 Choropleth Map visualizes U.S. county poverty rates for 2023. Each county is filled with a color from a threshold-based scale indicating the percentage of the population in poverty, with state averages used where county data is missing. The map uses a geoAlbersUsa projection and draws county boundaries via d3.geoPath, with hover interactions revealing a tooltip. Data is sourced from a remote CSV and county geometries from the us-atlas package.

D3 - Choropleth

This choropleth map visualizes poverty rates across U.S. counties in 2022, with counties colored according to a blue sequential threshold scale and state boundaries overlaid in white. The visualization includes an interactive legend and a tooltip that displays county name, state, and poverty value on mouseover. The code uses d3.geoPath to render geographic shapes, d3.scaleThreshold with d3.schemeBlues for color mapping, and topojson.feature to process the US county data. Data is loaded from a CSV file and merged with US TopoJSON geometry, with the rendering handled in SVG.

A9 Choropleth Map in D3

This choropleth map visualizes poverty rates across U.S. counties, using a blue sequential color scale to encode the percentage of residents in poverty for 2021. County boundaries are rendered as SVG paths via `d3.geoPath()` from TopoJSON data, while color values are mapped from a CSV dataset joined by FIPS codes. The map includes a hover tooltip via SVG `<title>` elements, and missing data appears gray. It uses D3 v7, TopoJSON, and d3-legend for potential legend support.

test Choropleth map in D3

This choropleth map displays poverty estimates for US counties in 2021, with each county shaded according to its poverty rate using a blue sequential color scale and a legend with tick marks. The visualization also includes state boundary outlines overlaid on the county polygons. Built with D3 v5, the map uses `d3.json` to load TopoJSON data from the us-atlas collection and `d3.csv` to parse county-level poverty rates, then renders the geography via `d3.geoPath` and `topojson.feature`. The color encoding applies `d3.scaleThreshold` and `d3.schemeBlues`, while an axis legend is generated with `d3.axisBottom`.

A9 Choropleth

This choropleth visualizes U.S. county-level poverty rates for 2021, with each county colored along a threshold scale of green shades; hovering reveals a tooltip with the county name and its exact percentage. The map is rendered as SVG using D3 v7’s `d3.geoPath` and TopoJSON `topojson.feature` to draw county boundaries, while a separate mesh path outlines counties lacking data. Poverty data is loaded from a CSV via `d3.csv`, and the color legend is generated with the d3-legend library. The visualization also includes a title and uses a linear scale to position the legend.
