This choropleth map visualizes the global share of the population infected with HIV/AIDS for the year 2017, using a yellow-orange-red sequential color scale to indicate prevalence rates. Countries with missing data appear in grey, while the map is projected using d3.geoNaturalEarth1 and rendered as SVG paths. The visualization is built with React and D3 v7, loading world topology from TopoJSON and HIV prevalence data from an IHME CSV. Country codes are matched through a Wikipedia ISO code lookup table to link each dataset.

HIV/AIDS Choropleth Map

This choropleth map visualizes the global share of the population infected with HIV/AIDS for the year 2017, using a yellow-orange-red color scale to represent prevalence rates. Countries with missing data appear in gray. The visualization is built with React and D3 v7, using `geoNaturalEarth1` and `geoPath` to render world countries from TopoJSON data, with geographic graticules and interiors drawn as overlays. The data comes from a CSV file containing HIV prevalence statistics from IHME.

HIV/AIDS Choropleth Map

This choropleth map visualizes the global share of the population aged 15-49 infected with HIV/AIDS for the year 2017, using a yellow-to-red sequential color scale that intensifies with higher prevalence. Country boundaries come from the World Atlas TopoJSON, while prevalence data originates from an IHME CSV dataset, matched to country shapes via ISO numeric codes. The visualization is built with React, D3 v5’s `geoNaturalEarth1` projection and `geoPath` for rendering SVG paths, including graticules and interior borders. Missing data countries appear in gray.

HIV/AIDS Choropleth Map

This choropleth map visualizes the global share of the population infected with HIV/AIDS in 2017, using a yellow-to-red sequential color scale to indicate prevalence rates. It renders a Natural Earth projection with graticules and country borders, and colors each country based on data from the IHME dataset, with gray indicating missing values. The visualization is built with React and D3 v5, using `d3.geoPath` for map geometry, `d3.scaleSequential` with `interpolateYlOrRd` for color encoding, and TopoJSON to load world atlas boundaries.

HIV/AIDS Choropleth Map

A choropleth map visualizes global HIV/AIDS prevalence in 2017, with countries shaded along a yellow-orange-red sequential scale and gray indicating missing data. The visualization uses React with D3.js v7, employing `d3.geoNaturalEarth1` projection and `d3.geoPath` to render country shapes from TopoJSON world atlas data. HIV prevalence values are loaded from an IHME dataset and mapped to numeric country codes for accurate geographical association.

HIV/AIDS Choropleth Map

This choropleth map visualizes the share of the population aged 15-49 infected with HIV/AIDS in 2017, using a yellow-orange-red sequential color scale. Country boundaries and graticules are rendered with d3.geoPath and a geoNaturalEarth1 projection, while missing data is shown in gray. The visualization is built with React and D3 v5, pulling country shapes from World Atlas TopoJSON and HIV prevalence data from the IHME via CSV.

HIV / AIDS Choropleth Map

This HIV/AIDS choropleth map visualizes the percentage of the population aged 15-49 infected with HIV for the year 2017, using a yellow-orange-red sequential color scale to indicate severity. Countries without data appear in grey. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render the world map, with graticules and country interiors drawn for context. React manages the component state, while d3.csv fetches the HIV prevalence data from the IHME dataset and d3.json loads the World Atlas TopoJSON.

HIV/AIDS Choropleth Map

This interactive choropleth map visualizes the global share of the population infected with HIV/AIDS in 2017, using data from OurWorldInData. Countries are colored on a yellow-to-red sequential scale based on prevalence, with gray indicating missing data. The visualization is built with React, rendering SVG shapes through d3.geoPath and a geoNaturalEarth1 projection, while d3-geo graticules and topojson mesh outlines delineate geographic boundaries. Country codes from the ISO-3166 dataset link the CSV data to world-atlas map features.

HIV/AIDS choropleth map

This choropleth map visualizes the global share of the population infected with HIV/AIDS for the year 2017, using a yellow-to-red sequential color scale to encode prevalence. The visualization renders country polygons via `d3.geoPath` with a Natural Earth projection, overlaying graticule lines and interior borders. Data from the IHME dataset is joined to map features through ISO alpha-3 to numeric country codes, with missing countries shown in gray. The React component uses `d3.scaleSequential` and `d3.interpolateYlOrRd` for color encoding, with TopoJSON from world-atlas providing the geographic boundaries.
