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.

Missing Migrants on a Map

A world map visualizes the locations and magnitudes of missing migrant incidents, with semi-transparent circles sized by the total number of dead and missing per coordinate. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` for land and graticule rendering, while a square-root scale maps incident counts to circle radii. React manages the component state, loading CSV data and world-atlas TopoJSON via hooks. The SVG rendering provides a clean overview of global migration-related fatalities.

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 displays the locations of missing migrants, with semi-transparent circles sized by the total number of dead and missing per incident. 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

This interactive visualization maps recorded incidents of missing migrants worldwide, with each circle representing an event and its radius scaled by the total number of dead or missing individuals. Using a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, the map renders country boundaries, graticules, and points from CSV data loaded with `d3.csv`. Circle sizes are determined by a square-root scale (`scaleSqrt`) applied to the death toll, and the React-based component structure uses `useWorldAtlas` to fetch TopoJSON land and interior boundaries.

Missing Migrants on a Map

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 Dataset - Map

A world map uses semi-transparent circles to show the geographic distribution of missing migrant incidents, with circle size scaled by the total dead and missing count via a square-root scale. The visualization is rendered in React with SVG, using d3.geoNaturalEarth1 for projection, d3.geoPath for map features, and d3.geoGraticule for grid lines. Data comes from a CSV of missing migrant records, while country boundaries come from the world-atlas TopoJSON dataset.
