dv2020-ep43-viz44 - missing migrants map & histogram (cleaned up)

dv2020-ep41-viz43 - missing migrants map & histogram

This visualization combines a bubble map and a histogram to explore the Missing Migrants Dataset. The map uses a Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to plot incident locations, with circle radii scaled by the square root of the "Total Dead and Missing" count using `scaleSqrt`. A histogram below bins the same data by reported date, aggregating monthly totals with `d3.histogram` and `timeMonths`. Both charts are rendered as SVG within a React component, pulling geographic and CSV data from external URLs.

dv.43 - missing migrants - part V - multi-view cleanup

A composite visualization of the Missing Migrants Dataset combines a world map with a monthly histogram. The map uses a natural Earth projection to plot incidents as scaled circles, with geographic lines overlaid. The histogram below displays monthly death tolls. Built with React, the visualization employs D3 modules including `geoPath`, `scaleSqrt`, `scaleTime`, and `bin` for histograms, rendering data from CSV and TopoJSON sources.

dv2020-ep44-viz45 - missing migrants brushing

A bubble map and histogram visualize the Missing Migrants Dataset, showing the geographic distribution and monthly counts of dead and missing migrants. The histogram uses a brushing interaction via `d3.brushX` to filter the map’s bubbles by date range. The map is rendered with `d3.geoPath` and a natural Earth projection, while data is loaded through `d3.csv` and world map topology via `d3.json` with TopoJSON. The React-based interface uses D3 scales and SVG elements for rendering.

dv2020-ep40-viz42 - missing migrants bubble map

A bubble map visualizes global migration incidents from the Missing Migrants Dataset, with circle size encoding the total dead and missing per location. The visualization uses a React component structure with D3’s `geoNaturalEarth1` projection and `geoPath` to render country boundaries, graticules, and shorelines from TopoJSON world-atlas data. A `scaleSqrt` maps data values to circle radii, while SVG circles are positioned via the projection coordinates. Interactive updates are handled through React state and hooks, with data loaded asynchronously via D3’s `csv` and `json` functions.

Missing Migrants on a Map and Histogram

The visualization combines a world map and a time-series histogram to show the locations and monthly counts of missing migrants. The bubble map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render land and graticules, with circle sizes scaled by `d3.scaleSqrt` based on the ‘Total Dead and Missing’ value. The histogram uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.histogram` with monthly bins, displaying the same metric over time. Data comes from a CSV of Missing Migrants, and the SVG is rendered using React with D3 v5.

dv.45 - missing migrants - part VII - make it fast!

This interactive visualization maps global migrant deaths and disappearances, with bubble size representing the total dead and missing per location. A linked time-series bar chart below displays monthly totals and incident counts, with a brushed time range filtering the map’s data. Built with React and D3, it uses `d3-geo` projections via `geoNaturalEarth1` and `geoPath`, `d3-scale`’s `scaleSqrt`, and `d3-brush` for the histogram selection. Data comes from the Missing Migrants Dataset.

dv2020-ep45-viz46 - missing migrants brushing - optimized

This visualization combines a bubble map and a time-series histogram to explore the Missing Migrants Dataset, with brushing linking the two views. The map uses d3.geoNaturalEarth1 and d3.geoPath to render country borders, shorelines, and graticules, with circle sizes scaled by d3.scaleSqrt. The histogram aggregates monthly totals via d3.histogram, while d3.brushX enables selecting a date range that filters the map’s bubbles. React manages state for the brush selection, and SVG renders all elements.

dv2020-ep39-viz41 - missing migrants histogram

This histogram visualizes the total dead and missing migrants over time, with monthly bins from the Missing Migrants Dataset. The visualization uses a React and D3 v5 architecture, rendering SVG graphics with `scaleTime` for the x-axis and `scaleLinear` for the y-axis. The data is processed through D3's `bin` and `timeMonths` functions to aggregate counts into monthly sums, while `csv` loads the dataset asynchronously via a custom `useData` hook.
