A world map displays incidents of missing migrants, with semi-transparent circles sized by the total number of dead and missing at each location. The visualization uses a natural Earth projection via `geoNaturalEarth1` and renders country boundaries, graticules, and the sphere through `geoPath`. Circle radii are scaled with `scaleSqrt` based on the maximum value. React manages the component state, while `useWorldAtlas` and `useData` load TopoJSON land and interior mesh data alongside a CSV of migrant incidents, all rendered as SVG elements.

AI-generated description

A world map showing cities with population greater than 50,000. City data from Simplemaps: World Cities Database.

Country boundaries from World Atlas TopoJSON, polished for visual style, including graticules.

Dataviz 2020_Ep40 - 32. Missing Migrants3 - Sized Circles on a Map

A world map displays circles sized by the number of total dead and missing migrants, with data from a CSV of global migrant incidents. The visualization uses a natural Earth projection rendered as SVG via React, with D3’s `geoPath` and `geoGraticule` for map outlines. Circle radii are scaled using a square-root scale (`scaleSqrt`) based on the maximum value, and the map layers include land, interiors, and sphere boundaries.

Missing migrants on a Map

This visualization maps the global distribution of missing migrants, with each semi-transparent circle scaled proportionally to the reported number of dead and missing individuals per incident. The map uses a natural Earth projection rendered via `d3.geoNaturalEarth1` and `d3.geoPath`, with landmasses, graticules, and country interiors drawn from TopoJSON data. Circle radii are determined by a `d3.scaleSqrt` function applied to the 'Total Dead and Missing' field from a subset of the Missing Migrants dataset. React manages the asynchronous loading of both the world atlas and CSV data, while SVG renders all visual elements.

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 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 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 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 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

This visualization maps the global distribution of missing migrants, with circle size proportional to the total number of dead and missing individuals per location. It uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render landmasses, graticules, and country boundaries from TopoJSON data. Migrant incident coordinates are projected and drawn as semi-transparent circles scaled with `d3.scaleSqrt`. The data comes from a CSV of the Missing Migrants Project, processed through React hooks and rendered as SVG.
