This example renders a horizontal bar chart of the top 10 most populous countries using UN population data for 2020. The visualization uses D3 v7 scales (`scaleBand` for countries, `scaleLinear` for population) within a React 18 component, drawing SVG rectangles whose widths encode population values. Grid lines and axis tick labels are generated from the linear scale's ticks, with country names positioned along the y-axis. The data is loaded asynchronously via `d3.csv` from a GitHub Gist.

UN Population

This example visualizes the top 10 countries by population in 2020 using a horizontal bar chart rendered with SVG. It loads UN population data from a CSV file via `d3.csv` and uses React hooks (`useState`, `useEffect`) to manage the asynchronous data loading. The chart employs `d3.scaleBand` for the y-axis country labels and `d3.scaleLinear` for the x-axis population values, with gridlines generated from `xScale.ticks()`.

UN Population Bar Chart Refactored

This example shows a horizontal bar chart of the top 10 most populous UN countries for 2020, with country names labeled on the y-axis and population counts on the x-axis. The visualization is rendered as SVG in a React component, using D3 v6 scales (scaleBand and scaleLinear) to map data, with separate XAxis and YAxis components drawing gridlines and tick labels. Data loads asynchronously from a CSV file via d3.csv in a custom useData hook, and React manages the component lifecycle.

UN population countries

A bar chart displays the top 10 most populous countries in 2020 using UN population data, with horizontal bars sized by `Population` values. The React app loads CSV data via `d3.csv`, filters the first ten rows, and renders SVG `<rect>` elements using `d3.scaleBand` for the y-axis country categories and `d3.scaleLinear` for the x-axis population scale. The chart updates after an asynchronous data fetch, showing a loading state before the visualization appears.

UN Population Bar Chart

This visualization displays the top 10 most populous countries in 2020 as horizontal bars, with bar length proportional to population. The React component loads the UN population dataset via d3.csv, then renders an SVG using scaleBand for the categorical country axis and scaleLinear for the population values. The chart fills the entire browser window (width and height set to window dimensions) and updates only after the data loads, initially showing a large “Loading…” message. The code uses React hooks (useState, useEffect) to manage the asynchronous data fetching and D3’s scale functions for mapping data to pixel coordinates.

UN population graph

This visualization displays the top 10 most populous countries using horizontal bars, ordered by country name with population shown on the x-axis in billions. The chart is built with React and D3 v5, using `scaleBand` for the categorical y-axis and `scaleLinear` with a maximum domain for the numeric x-axis. Data comes from the UN Population 2019 CSV, loaded via `d3.csv`, and rendered as SVG. Axis components and tick marks are generated from `d3.ticks`, formatted with `d3.format`, with tooltips showing exact values via SVG `<title>` elements.

UN data

This bar chart displays the top ten countries by population in 2020, based on UN population data loaded from a CSV file. The visualization uses React for component structure and D3 v7 for scales, axes, and SVG rendering. The `scaleBand` positions the country labels on the y-axis, while `scaleLinear` maps population values to bar widths, with gridlines and tick labels generated from the x-scale. The data is fetched asynchronously via `csv()` and sorted alphabetically before being rendered as SVG rectangles.

United Nations Data for World Population

This example visualizes the top 10 most populous countries in 2019 using a horizontal bar chart. The chart loads United Nations population data from a CSV file via `d3.csv` and processes each row to extract the `2019` population value. React state manages the loaded data, and D3’s `scaleBand` and `scaleLinear` position and size the SVG rectangles. The visualization is rendered with React and SVG, showing population counts as bar widths.

United Nations Bar Chart

This example displays a horizontal bar chart of the top 10 most populous countries in 2019 using data from the United Nations. React manages the component state, loading CSV data via d3.csv, while D3’s scaleBand and scaleLinear map country names and population values to screen coordinates. The SVG rectangles are rendered dynamically in a React map function, with bar widths proportional to each country’s estimated 2020 population. The visualization updates once data is fetched, showing a clean, static comparison of national population sizes.
