Missing Migrants on a Map

Missing Migrants on a Map

This visualization shows the global distribution of missing migrants, with circles sized by the total number of dead and missing individuals at each recorded location. The map uses a natural Earth projection rendered as SVG paths via d3.geoPath, with graticules and country borders from TopoJSON world-atlas data. Migrant locations are loaded from a CSV file, projected through d3.geoNaturalEarth1, and plotted as semi-transparent circles scaled by d3.scaleSqrt. React manages the component state and rendering, while d3's max function determines the domain for the size scale.

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 visualization maps the global locations of missing migrants, with semitransparent circles sized proportionally to the total number of dead and missing at each coordinate. The map uses a natural Earth projection rendered with d3.geoPath, combining world landmasses, graticules, and country borders from the world-atlas TopoJSON dataset. The CSV data is loaded and parsed with d3.csv, while d3.scaleSqrt maps the migrant counts to circle radii. The React component structure uses useState and useEffect hooks to fetch and display the data as SVG circles.

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 map visualization shows the global distribution of missing migrants, with the size of each circle representing the total number of dead and missing individuals at a given location. The visualization uses a natural Earth projection and overlays semi-transparent circles on a world map, alongside graticules and country borders for geographic context. Built with React and D3 v5, the code employs `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule` to render the map, while a square root scale (`d3.scaleSqrt`) maps the migrant counts to circle radii. Data comes from a CSV file of the Missing Migrants Project, with geographic coordinates parsed and projected onto the SVG canvas.

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

This visualization maps missing migrant incidents worldwide using a natural Earth projection. Circles sized by the square root of the total dead and missing count are overlaid on geographic landmasses and graticules, with opacity highlighting incident density. It uses React for component structure, d3.geoNaturalEarth1 and d3.geoPath for projection and rendering, d3.scaleSqrt for radius encoding, and topojson to convert world atlas data. The dataset comes from the Missing Migrants CSV, with coordinates parsed and reversed for plotting.

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.
