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.

Choropleth Map

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.

HIV/AIDS Choropleth Map

This choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15–49 in 2017, using a yellow-orange-red sequential color scale. The code employs React with D3 v6’s `geoNaturalEarth1` projection and `geoPath` to render SVG country shapes, while `d3.scaleSequential` and `interpolateYlOrRd` map data values to colors. Countries without matching data appear gray, and the map includes graticules and interior borders. Data is sourced from IHME via CSV, with country codes matched using ISO-3166 metadata.

HIV/AIDS Choropleth Map

This choropleth map displays the global prevalence of HIV/AIDS among adults aged 15–49 for the year 2017, using a sequential yellow-orange-red color scale to indicate infection rates. Countries with missing data appear in grey. The visualization renders world countries as SVG paths using d3.geoPath with a geoNaturalEarth1 projection, overlaid with graticule and interior boundaries. Data from the IHME CSV is joined to country geometries via ISO numeric codes, while React manages the application state.

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.

HIV/AIDS Choropleth Map

This choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017, using a sequential yellow-to-red color scale to indicate infection rates. Countries without data appear in gray. The visualization is built with React and D3 v7, using `geoNaturalEarth1` projection, `geoPath` to render country boundaries, and `geoGraticule` for the latitude/longitude grid. Data comes from IHME, joined to country shapes via ISO numeric codes loaded from a CSV.

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

This visualization shows the global prevalence of HIV/AIDS among adults aged 15-49 in 2017, with countries colored on a sequential yellow-orange-red scale from the d3.scaleSequential and interpolateYlOrRd APIs. The map uses d3.geoNaturalEarth1 projection with d3.geoPath to render SVG paths of world countries, with missing data shown in gray. Country codes are matched via a lookup table from a CSV file, and the choropleth is built using React components that fetch data with d3.csv and d3.json.

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.
