UN Population Bar Chart v2

UN Population Bar Chart v3

This visualization displays the populations of the top ten countries from a UN 2020 dataset as horizontal bars, using a bar chart format. The chart scales population values linearly on the x-axis and country names using a band scale on the y-axis. Built with React and D3 v7, it loads the CSV data via `d3.csv` and renders SVG elements directly, including axis ticks and grid lines. The visualization fills the browser window and updates asynchronously once the data is fetched.

UN Population Bar Chart v4

This bar chart displays the 20 most populous countries in 2020, ranked vertically by country with horizontal bars proportional to population size. The visualization uses React components with D3 v7 scales, including `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Data is loaded via D3’s `csv` function from a GitHub-hosted dataset, with axes rendered as custom SVG elements using `AxisBottom` and `AxisLeft`.

UN Population Bar Chart v5

This horizontal bar chart displays the 20 most populous countries in 2020, with bars extending left-to-right from a shared baseline. The visualization uses D3 v7’s scaleBand and scaleLinear to map country names to y-axis positions and population values to bar widths, rendered as SVG rectangles in React. The data is loaded from a remote CSV, with tick labels formatted using D3’s format function, converting values to billions. The chart includes styled axes and a population label, with hover tooltips provided by native SVG `<title>` elements.

UN Populations

A horizontal bar chart displays the ten most populous UN countries for 2020, with country names on the y-axis and population counts on the x-axis. Built with React and D3.js v6, it loads CSV data via `d3.csv` and renders SVG rectangles scaled by `d3.scaleLinear` and `d3.scaleBand`. Axis ticks and labels are generated from `xScale.ticks()`, producing a clean, grid-lined comparison of national populations.

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 Bar Chart

This example shows a horizontal bar chart of the top 10 countries by population from the UN’s 2019 dataset. It uses React state to load and store the CSV data, while D3’s `scaleBand`, `scaleLinear`, and `max` utilities compute the bar positions and widths. The SVG bars render across the full window height, sized proportionally to each country’s 2020 population. The code loads the data asynchronously with `d3.csv` and displays a loading message before the chart appears.

UN Population Data

A horizontal bar chart displays the populations of ten countries in 2020, sourced from UN data loaded via a CSV file. The visualization uses React to render SVG elements, with D3 v6 scales (scaleBand and scaleLinear) positioning bars and axes. Custom React components handle the axes and bars, with native SVG `<title>` elements providing tooltips. Population values are formatted using D3's `format` function, converting values like billions into abbreviated labels.

UN World Population 2020

A horizontal bar chart displays the top 10 most populous countries in 2020 according to UN data. Each bar’s length encodes the country’s population, scaled linearly using `d3.scaleLinear`, while the vertical bands use `d3.scaleBand`. The data loads asynchronously via `d3.csv` from a GitHub gist, and React renders the SVG rectangles. The code imports `csv`, `arc`, `pie`, and `max` from D3 v7.
