A choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017. Countries are filled with a yellow-orange-red sequential color scale from `d3.scaleSequential` and `interpolateYlOrRd`, with gray for missing data. The map uses `d3.geoNaturalEarth1` projection and `d3.geoPath` on TopoJSON data from the World Atlas, rendering country boundaries and graticules via SVG. HIV prevalence data comes from IHME, joined to country codes via ISO-3166 reference data.

AI-generated description

A world map showing cities with population greater than 50,000. City data from Simplemaps: World Cities Database.

Country boundaries from World Atlas TopoJSON, polished for visual style, including graticules.

Choropleth Map

This choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017. Countries are colored on a yellow-orange-red sequential scale using d3.scaleSequential with interpolateYlOrRd, with gray indicating missing data. The map uses d3.geoNaturalEarth1 projection, d3.geoPath, topojson features for country boundaries, and a geoGraticule overlay. Data comes from IHME prevalence statistics loaded via d3.csv, rendered as SVG paths in a React framework.

HIV/AIDS Choropleth Map

A choropleth map displays HIV/AIDS prevalence among adults aged 15–49 for the year 2017, with countries colored on a yellow-orange-brown sequential scale from `d3.scaleSequential` and `interpolateYlOrBr`, while nations lacking data appear gray. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries, graticules, and interiors from a TopoJSON world atlas. Data comes from a CSV of population infection rates, joined to countries via ISO numeric codes; React manages the component state and rendering as an SVG.

Choropleth map

A choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017, with countries colored on a yellow-orange-red sequential scale using d3.scaleSequential and interpolateYlOrRd. Gray marks indicate missing data. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render SVG paths from TopoJSON world atlas data, with country codes matched to CSV data from the IHME via ISO numeric codes. React manages the component lifecycle, loading data asynchronously through custom hooks.

HIV/AIDS Choropleth Map

A choropleth map visualizes global HIV/AIDS prevalence among adults aged 15-49 in 2017, with countries shaded on a yellow-to-red sequential color scale and missing data highlighted in red. Built with React and D3 v7, it uses `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries and graticules from TopoJSON world atlas data, while CSV data from IHME is joined to countries via ISO numeric codes. The map employs `d3.scaleSequential` with `interpolateYlOrRd` for color encoding.

HIV/AIDS Choropleth Map

A choropleth map shows the global prevalence of HIV/AIDS among adults aged 15-49 for the year 2017, using a yellow-to-red sequential color scale where darker shades indicate higher infection rates. Countries with missing data appear in light gray. The visualization is built with React and D3 v7, using `geoNaturalEarth1` and `geoPath` for map projection, `geoGraticule` for grid lines, and TopoJSON world atlas data. The choropleth applies a `scaleSequential` with `interpolateYlOrRd` to color each country polygon.

HIV/AIDS Choropleth Map

A choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017, with countries colored on a sequential yellow-to-red scale based on infection rates. Missing data renders in gray. Built with React and D3 v6, the map uses `geoNaturalEarth1` and `geoPath` to project world atlas TopoJSON data, while CSV data from the IHME is joined to country codes via a lookup table.

Choropleth Map

This choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017, using a yellow-orange sequential color scale where darker shades represent higher infection rates. Countries with missing data appear in grey. Built with React and D3 v5, the visualization loads world country boundaries from a TopoJSON dataset and HIV prevalence data from a CSV file. The code projects geographic coordinates using `geoNaturalEarth1`, renders country shapes with `geoPath`, and overlays graticules via `geoGraticule`.

HIV / AIDS Choropleth map

A choropleth map displays HIV/AIDS prevalence among adults aged 15–49 by country for the year 2017, using a yellow-orange-red sequential color scale. Countries with missing data are rendered in gray. The visualization uses React with d3-geo for the Natural Earth projection and geoPath, and d3-scale-chromatic for color interpolation. Data comes from the IHME HIV/AIDS dataset, loaded via d3.csv, and country boundaries are drawn from World Atlas TopoJSON using topojson.feature and topojson.mesh.
