This streamgraph shows the total number of persons of concern to UNHCR over time, grouped by country of origin, with each colored band representing a country. Using D3.js v4, it employs `d3.stack` with `d3.stackOffsetWiggle` and `d3.stackOrderInsideOut` to create the layered layout, and `d3.area` with `d3.curveBasis` for smoothed curves. Data from the UNHCR Population Statistics API is loaded via `d3.json`, and labels are positioned using the `d3-area-label` library. The visualization filters to countries with over one million total persons of concern and renders as an SVG.

AI-generated description

A StreamGraph visualization of the total number of persons of concern grouped by country of origin.

The total number of persons of concern is the sum of Asylum-seekers, Internally displaced persons, Persons in IDP-like situation, Others of concern, Returned IDPs, Refugees (incl. refugee-like situations), Returnees, Persons in Refugee-like situation, and Stateless Persons. Excludes countries with relatively low counts. Data from UNHCR Population Statistics.

See also this variant that shows the data grouped by destination.

Draws from Labeled Streamgraph and Syrian Refugees by Settlement Type.

Uses d3-area-label to position labels.

Persons of Concern StreamGraph by Origin

This streamgraph visualization shows the total number of UNHCR persons of concern over time, grouped by country of origin, using d3.stack with the stackOffsetWiggle algorithm to create layered flowing areas. It includes interactive hover effects that highlight individual paths, with labels positioned via d3-area-label. The chart interpolates missing yearly data using d3.bisector and renders as SVG, with major and minor time axes. Data comes from UNHCR Population Statistics, filtered to exclude countries with relatively low counts.

Persons of Concern StreamGraph by Origin

This streamgraph visualizes the total number of persons of concern, grouped by country of origin, over time, using data from UNHCR Population Statistics. The graphic displays the changing volume of various categories—such as refugees, asylum-seekers, and internally displaced persons—as stacked, colored streams, with labels repositioned using d3-area-label. The visualization employs D3 v4’s `d3.stack`, `d3.area`, and `d3.curveBasis` to render the smoothed, wiggle-offset streams, while `d3.scaleTime` and `d3.scaleLinear` handle the axes. The SVG rendering uses a filter to exclude countries with low total counts, and the streams highlight on hover.

Persons of Concern StreamGraph by Origin

This StreamGraph visualizes the number of persons of concern over time, grouped by country of origin, using data from UNHCR Population Statistics. A stack offset wiggle creates the flowing layers, with d3.area-label placing labels inside each region. The code uses d3.stack, d3.scaleTime, and d3.curveBasis to render the SVG, with interpolated values between annual data points. Major and minor axes display time, while hovering highlights individual country streams.

Persons of Concern StreamGraph by Origin

A streamgraph displays the total number of persons of concern (refugees, asylum-seekers, internally displaced persons, and others) over time, grouped by country of origin, with labels placed inside each area using the `d3-area-label` library. The visualization uses D3.js v4 with an SVG rendering, applying `d3.stack` with a wiggle offset and inside-out ordering to create the stacked areas. Data comes from UNHCR Population Statistics and is interpolated across years. The chart includes hover effects that darken each area and uses `d3.scaleTime` and `d3.scaleLinear` for axes.

Persons of Concern StreamGraph by Origin

This streamgraph shows the total number of persons of concern—including refugees, asylum-seekers, and internally displaced persons—grouped by country of origin over time, drawing on UNHCR population statistics. The visualization uses d3.stack with a wiggle offset to create the layered streams, and d3.area-label to place labels inside the curves. Data is interpolated across years to produce continuous paths, with hover effects altering fill opacity. Excluding low-count countries, the chart renders as an SVG with a time-based x-axis and a stacked area layout.

A streamgraph shows the total number of persons of concern, such as refugees and internally displaced people, grouped by country of origin over time, excluding countries with relatively low counts. The visualization uses a wiggle offset and inside-out ordering to stack the areas, with labels positioned by d3-area-label. Data comes from UNHCR Population Statistics, interpolated across years and rendered as SVG using d3.v4's stack and area APIs.

Fork of Persons of Concern StreamGraph by Origin

This streamgraph visualizes the total number of persons of concern grouped by country of origin, with data from UNHCR Population Statistics. Each colored band represents a country, with labels positioned using d3-area-label. The visualization uses d3.stack with stackOffsetWiggle and stackOrderInsideOut to create the flowing streamgraph shape, while d3.scaleTime and d3.scaleLinear handle the axes. The code interpolates yearly values using d3.bisector, and renders the result as an SVG with hover effects that highlight individual bands.
