Missing Migrants - Multiple Views w Brushing

Missing Migrants Multiple Views, with Brushing

This example visualizes missing migrant incidents worldwide with a bubble map and a brushing-linked date histogram. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries and graticules, with circle sizes scaled by `d3.scaleSqrt` to represent the total dead and missing per incident. The histogram, built with `d3.bin` and `d3.scaleTime`, shows monthly totals and supports brushing via `d3.brushX`; when a date range is selected, the map filters its circles to matching incidents. Both views share data from a CSV of global missing migrants, rendered as SVG within React.

Missing Migrants - Multiple Views with Brushing

A world map and a time-series bar chart display data on migrants who died or went missing, sourced from the United Nations Missing Migrants project. The map uses a `geoNaturalEarth1` projection with `geoPath` to render landmasses, while circles sized by `scaleSqrt` represent casualty counts. A brushing interaction on the date histogram, implemented with `brushX`, filters the map’s circles to the selected time period based on `Reported Date`. SVG elements render both views.

Missing Migrants Multiple Views with Brushing

This interactive visualization combines a natural Earth projection bubble map of missing migrants with a linked brushing-enabled date histogram. The map uses d3.geoNaturalEarth1 and d3.geoPath to render world landmasses from TopoJSON, with circle radii scaled by d3.scaleSqrt based on total dead and missing counts. The histogram bins monthly totals via d3.bin and d3.timeMonths, and the d3.brushX selection filters map circles in real time. Both views use SVG rendering within a React framework, loading data from a CSV of Missing Migrants Global incidents.

Brushing Missing Migrants Multiple Views

This interactive visualization combines a world map and a time-series histogram to explore missing migrant incidents. Users can brush over the histogram to filter the map, which displays proportional circles sized by the total number of dead and missing individuals. The map uses a natural Earth projection with graticules and country borders, rendered with SVG via React. Data comes from the Missing Migrants Project and is aggregated by month using d3.bin. The linked views are implemented with d3.scaleSqrt for circle sizing and d3.brushX for the interactive selection.

Missing Migrants (part 6) : Multiple Views with Brushing

Two coordinated views of migrant deaths worldwide from the Missing Migrants Project dataset show a world map with proportional circles and a time-series histogram. Brushing a time range in the histogram with `d3.brushX` filters the map’s circles to incidents within that period. The map uses `geoNaturalEarth1` and `geoPath` for the sphere, graticule, and landmasses, while the histogram bins monthly totals via `d3.bin` and `timeMonths`. Both views render in SVG with React.

Missing Migrants Multiple Views with Brushing

This interactive visualization combines a bubble map and a date histogram to explore global missing migrant incidents. Users brush over the histogram to filter the map, revealing the geographic distribution of deaths and missing persons within a selected time range. The map uses a natural Earth projection with proportional circle sizes for death counts, while the histogram aggregates monthly totals. Built with D3.js v7 and React, it employs `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.bin`, `d3.brushX`, and `d3.scaleSqrt` for data processing and rendering as SVG elements. Data comes from a CSV of Missing Migrants Global incidents.

Missing migrants multiple views with brushing

The visualization presents global migrant deaths and disappearances through two linked views: a bubble map and a time-series histogram. Brushing a time range on the histogram filters the map’s circles, which are scaled by the square root of the death count. Built with React, it uses D3 v7 APIs including `geoNaturalEarth1`, `geoPath`, `scaleSqrt`, `brushX`, and `bin`. Data comes from a CSV of Missing Migrants records, rendered as SVG marks over world atlas topography.

Missing Migrants Multiple Views with Brushing

This visualization combines a bubble map and a date histogram to explore global missing migrant data from a CSV dataset. Users can brush across the histogram to filter the map by date range, with linked views updating simultaneously. The map uses d3.geoNaturalEarth1 projection and d3.geoPath for country boundaries, while the histogram applies d3.bin with timeMonths thresholds and d3.brushX for selection. React manages state for the brush extent, and d3.scaleSqrt sizes bubbles by the total dead and missing count.
