This example shows a brushing interaction between a bubble map and a time-series histogram. Users can brush over the histogram to filter which cities appear on the map, with circle sizes encoding the total number of dead and missing migrants. The visualization uses React to manage state and D3 v5 APIs including `geoNaturalEarth1`, `geoPath`, `brushX`, and `scaleSqrt`. Data comes from the Missing Migrants Project, with map boundaries from World Atlas TopoJSON and rendering via SVG.

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.

Brushing

This example links a bubble map and a date histogram to explore missing migrant incidents. The map projects circles sized by the total dead and missing using d3.geoNaturalEarth1 and d3.geoPath, while the histogram bins monthly counts with d3.bin and d3.scaleTime. Users can brush the histogram with d3.brushX, which dynamically filters the map's circles to show only incidents within the selected date range. Data comes from a CSV of reported migrant deaths, and the visualization is built with React and rendered as SVG.

This example demonstrates linked brushing between a world bubble map and a time-series histogram, both rendered as SVG in React. The map plots migrant deaths and missing persons by location with circle radii scaled by d3.scaleSqrt, while the histogram aggregates the same metric monthly using d3.bin and d3.timeMonths. Brushing the histogram with d3.brushX filters the map’s displayed circles in real time. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for the map projection, and loads data from a CSV of the Missing Migrants Global 2019 subset.

This example shows a world map with bubble markers indicating the total number of dead and missing migrants, alongside a time-series histogram of the same data. Brushing a date range in the histogram filters the bubbles shown on the map. The visualization uses React state to manage the brush selection, D3’s `geoNaturalEarth1` projection and `geoPath` for the map, `scaleSqrt` for bubble sizing, and `brushX` for interactive filtering. Data comes from a CSV of migrant incidents loaded via `d3.csv`.

This example pairs a natural Earth bubble map with a time-series histogram, both rendered as SVG, to visualize global migrant deaths and disappearances. Brushing on the histogram filters the map’s circles in real time, showing only incidents within the selected date range. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` for projections and country boundaries from TopoJSON, while the histogram aggregates monthly totals with `d3.bin` and `d3.sum`. Data comes from the Missing Migrants Project, with circle sizing scaled by `d3.scaleSqrt`. React manages state, and D3’s `brushX` drives the interactive filtering.

Miltiple views with brushing

This example shows a linked brushing interaction between a date histogram and a world map of migrant deaths, where dragging a brush across the time axis filters the bubbles displayed on the map. The histogram aggregates monthly totals using d3.bin and d3.sum, while the map projects coordinates with d3.geoNaturalEarth1 and d3.geoPath. The brush is implemented with d3.brushX, and updates are triggered via React state. Data comes from a CSV of missing migrants, and the world atlas is loaded from TopoJSON.

This example combines a geographic bubble map with a time-series histogram, linked through interactive brushing. The map displays the total number of dead and missing migrants by location, with circle sizes scaled using d3.scaleSqrt, while the histogram aggregates the same data by month using d3.bin and d3.timeMonths. Dragging a brush across the histogram filters the map’s circles to show only incidents within the selected date range, implemented with d3.brushX and React state. Both views use SVG rendering via d3.geoNaturalEarth1 and d3.geoPath for the map, with data sourced from the Missing Migrants Project CSV.

Map and Histogram with Brushing

This interactive visualization combines a world map of bubble markers with a linked time-series histogram, allowing users to brush over a date range to filter the geographic data. It plots migrant deaths and disappearances from a global dataset, with bubble size scaled by the square root of the count using `d3.scaleSqrt`. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` with TopoJSON world atlas data. Brushing is implemented with `d3.brushX`, and the React components re-render filtered circles accordingly. The histogram is built with `d3.bin` and `d3.timeMonths`.

This example shows a world map of missing migrant incidents, with bubbles sized by the total number of dead and missing. A time-series histogram below the map displays the same data binned by month. Brushing the histogram filters the map’s bubbles in real time. The visualization uses React for the component structure and `d3.geoNaturalEarth1` with `d3.geoPath` for the map, alongside `d3.brushX` and `d3.scaleTime` for the interactive filtering.
