A world map displays the locations of missing migrants, with each incident represented by a semi-transparent circle whose area encodes the total number of dead and missing. The visualization uses a Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, rendering landmasses, graticules, and country borders from World Atlas TopoJSON. Circle radii are scaled with `d3.scaleSqrt` based on the data’s maximum value from the Missing Migrants Project CSV. The example is built in React, using `useEffect` to load TopoJSON and CSV data through `d3.json` and `d3.csv`, with SVG output.

Missing Migrants on a Map

A world map displays the locations of missing migrant incidents, with semi-transparent circles sized by the total number of dead and missing per event. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and renders landmasses, graticules, and country borders using `d3.geoPath`. Circle radii are scaled with a square-root scale `d3.scaleSqrt` based on the dataset from the Missing Migrants Project, loaded as CSV. The React app fetches world atlas TopoJSON and the CSV data through custom hooks.

Missing Migrants on a Map

A world map visualizes missing migrant incidents, with each semi-transparent circle representing a single event and sized proportionally to the total number of dead and missing. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render landmasses, graticules, and country boundaries from World Atlas TopoJSON. Circle radii are scaled using `d3.scaleSqrt`, and the data comes from the Missing Migrants Dataset CSV, processed with React hooks and rendered as SVG.

The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with graticules and country boundaries from World Atlas TopoJSON. Circle radii are scaled using `d3.scaleSqrt` based on the maximum death toll, and React manages the SVG rendering. Data comes from the Missing Migrants Global 2019 CSV, loaded with `d3.csv`.

Missing Migrants on a Map

A world map displays the locations of missing migrant incidents, with semi-transparent circles sized by the total number of dead and missing individuals. The visualization uses D3’s geographic projections (`geoNaturalEarth1`, `geoPath`, `geoGraticule`) combined with React and SVG rendering. Circle sizes are scaled with `scaleSqrt`, and the map includes land masses, interior borders, graticules, and a sphere background. Data comes from a CSV of Missing Migrants Global records, while world geography uses TopoJSON from the world-atlas package.

Missing Migrants on a Map

A world map displays the global distribution of missing migrants, with semi-transparent circles sized proportionally to the total number of dead and missing individuals at each location. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render land masses, graticules, and country interiors from TopoJSON data. Circle radii are scaled using `d3.scaleSqrt` based on the dataset's maximum value. The React component hierarchy manages asynchronous data loading with custom hooks for both the world atlas and the CSV dataset.

A world map displays the global distribution of missing migrants, with semi-transparent circles sized by the total number of dead and missing per location. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render landmasses, graticules, and country borders from TopoJSON data. Circle radii are scaled with `d3.scaleSqrt` based on the dataset's "Total Dead and Missing" values. The React component structure relies on the `useWorldAtlas` and `useData` hooks to load and process the world atlas and CSV data.

Missing Migrants on a Map

This visualization displays a world map of missing migrant incidents, with circle markers sized according to the total number of dead and missing individuals at each location. The map uses a natural Earth projection with graticules and country borders rendered as SVG paths, while circles are overlaid with square-root scaling for radius. Built with React and D3 v5, the example loads world atlas topology via the `topojson` library and pulls data from a CSV file. The `geoNaturalEarth1` projection and `geoPath` handle geographic mapping, while circles are positioned using the projection coordinates.

Missing Migrants on a Map

This map visualization displays the global distribution of missing migrants, with circles sized by the total number of dead and missing individuals per location. Using a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, it renders land masses, graticules, and country interiors as SVG paths. Circle radii are scaled with `d3.scaleSqrt` based on the data’s maximum value. The data is loaded asynchronously from a CSV using D3’s `csv` utility, while world map topology comes from a JSON file processed with TopoJSON’s `feature` and `mesh` functions. React hooks manage the loading state.
