Forked from Persons of Concern StreamGraph by Origin

This visualization shows the annual Air Quality Index (AQI) for 2015 across three Chinese cities—Tianjin, Shanghai, and Guangzhou—as a streamgraph with wiggling stacked areas. Each city’s monthly AQI values are interpolated to create smooth, colored bands. The visualization uses d3.stack with d3.stackOffsetWiggle and d3.stackOrderInsideOut to generate the layers, and d3.area with d3.curveBasis for rendering. Hovering over a path highlights it in black. The code loads data from a local AQI.json file and employs d3-scaleTime for the x-axis and d3-scaleOrdinal with d3.schemeCategory10 for colors.

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.

Draws from Labeled Streamgraph and Syrian Refugees by Settlement Type.

Uses d3-area-label to position labels.

AQI Over Time

This visualization tracks Air Quality Index (AQI) over time for Chinese cities, beginning with a series of hourly line charts for Beijing, and then shifting to a stacked area chart showing monthly AQI totals for Beijing, Tianjing, Shanghai, and Guangzhou. The first chart uses Vega-Lite and d3.csv to render the data, while the second employs d3.stack, d3.area, d3.areaLabel, and d3.scaleOrdinal to build the stacked areas. Both chart components are responsive, re-rendering on window resize to fill the available viewport.

API in Different Cities

This example shows hourly Air Quality Index (AQI) readings across multiple Chinese cities, with each city’s time series plotted as an area chart and stacked vertically for comparison. The visualization uses a Vega-Lite specification embedded via `vegaEmbed`, which declares temporal x-axes, quantitative y-axes, and row facets for city names. Data is loaded from a CSV file using `d3.csv`, and the chart re-renders on window resize by re-calling `vegaEmbed` with updated dimensions. The code references D3 v4 for data loading and Vega-Lite v2 for the visual encoding.

AQI in Different Cities

The visualization displays Air Quality Index (AQI) values as a heatmap across different cities and timestamps, with color intensity reflecting pollution levels. Each rectangular cell encodes a city-time pair, and tooltips reveal exact AQI numbers on hover. The code uses the d3.csv API to load the AQI_2015.csv dataset, then constructs the graphic through the Vega-Lite API (vl.markRect) with fields mapped to the x-axis, y-axis, color scale, and tooltip. The resulting SVG renderer output is configured with custom axis styling and tooltip handling via vegaTooltip.

The next 24 hours AQI in Beijing (line)

This visualization displays the Air Quality Index (AQI) forecast for Beijing over a 24-hour period, showing a clear upward trend. The line chart, rendered as an SVG using D3 v5, maps timestamps on the x-axis and AQI values on the y-axis. The code uses `d3.scaleTime` and `d3.scaleLinear` for axis scaling, `d3.line` with `curveBasis` for a smooth line, and `axisBottom` and `axisLeft` for tick marks. Data is loaded from a local CSV file.

The next 24 hours AQI in Beijing (area)

This area chart shows the predicted Air Quality Index (AQI) in Beijing over the next 24 hours, with time on the x-axis and AQI values on the y-axis. The smooth curve, generated using D3’s `area` generator with `curveBasis`, highlights rising pollution levels from evening to midday. The visualization loads hourly forecast data from a local CSV file and renders it as an SVG. Axes and gridlines are drawn with `axisBottom` and `axisLeft`, while `scaleTime` and `scaleLinear` map the data coordinates.

The next 24 hours AQI in Beijing (dot)

This dot chart displays Beijing’s Air Quality Index (AQI) forecasts for the next 24 hours, with each circle representing an hourly reading from March 25–26, 2020. The data comes from weather.com.cn and shows AQI values rising from 95 to a peak of 232 before declining. The visualization uses D3 v5 with `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` for gridlines, and SVG circles to plot points. Timestamps are parsed as JavaScript `Date` objects, and the chart includes labeled axes and a title.

Fork of AQI Data in America in 2021 with Histogram and Brushing

This visualization displays daily Air Quality Index (AQI) readings across the United States in 2021, combining a geographic scatterplot with a synchronized time-series histogram. Users can brush over the histogram to filter the map’s colored circles by date, with color intensity reflecting AQI levels. The map uses `d3.geoAlbersUsa` and `d3.geoPath` to render state boundaries, while the histogram employs `d3.bin`, `d3.scaleTime`, and `d3.brushX` for interactive selection. Data is loaded via `d3.csv` from a GitHub-hosted dataset, and React manages component state for the brushing extent.

Fork of AQI Data in America in 2021 with Histogram and Brushing

This interactive map of U.S. Air Quality Index (AQI) data for 2021 uses a d3.geoAlbersUsa projection with d3.geoPath to render state boundaries, while a quantitative color scale encodes AQI values at each monitoring site. A linked d3.brushX histogram below the map shows monthly mean AQI, and brushing a time range filters the map’s bubbles to show only data from that period. The visualization is built with React, uses d3.scaleQuantile for color mapping, and d3.histogram for binning, with data loaded via d3.csv from a GitHub source.
