This example shows a horizontal bar chart of the top 10 most populous countries, with population values on the x-axis and country names on the y-axis. Built with React components that render SVG elements, it uses `d3.scaleBand` for the y-axis categories and `d3.scaleLinear` for the x-axis range. The data is loaded with `d3.csv` from a GitHub-hosted dataset, and axes are drawn using custom React components that generate `<line>` and `<text>` elements.

Refactored Bar Chart

This example shows a horizontal bar chart of population data for the top ten countries, with a linear scale for population and a band scale for country names. It is built with React, D3 v7, and SVG, using custom components for the axes and bars. The data is loaded from a CSV file via D3's `csv` function, and the chart is rendered declaratively by mapping the dataset to SVG `rect` and `text` elements.

Refactored Bar Chart

A horizontal bar chart displays the top ten countries by population, using a React component structure to render SVG elements. The visualization is built with D3 v7’s scaleBand and scaleLinear for axes and scales, while custom React components manage the axis lines and bar marks. Data on population is loaded via CSV from a GitHub gist.

Refactored Bar chart

This example shows a horizontal bar chart of the top 10 countries by population for 2020, with countries listed along the y-axis and population values along the x-axis. The visualization uses React to render SVG elements, with D3 v6 providing scales and data loading. The code imports `csv` to fetch population data from a GitHub-hosted CSV file, `scaleBand` and `scaleLinear` to map country names and population values to pixel coordinates, and `max` to determine the x-axis domain. Axis components and bar marks are defined as individual React components for modularity.

Refactored Bar Chart

This example shows a horizontal bar chart of the top 10 countries by population for 2020, rendered as SVG via React components. It loads CSV data from a GitHub-hosted file using D3’s `csv` utility, then defines separate axis and mark components (`AxisBottom`, `AxisLeft`, `Marks`) that leverage D3’s `scaleBand` and `scaleLinear` for positioning. The chart uses React’s state and `useData` hook to fetch and transform the data, displaying a loading message until the data arrives.

Refactored Bar Chart

This example shows a horizontal bar chart of the top 10 countries by 2020 population, with the y-axis listing country names and the x-axis displaying population values. It loads data from a CSV file using `d3.csv` within a React hook (`useData`). The visualization uses `d3.scaleBand` and `d3.scaleLinear` to map data to SVG rectangles, with axes and marks extracted into reusable React components (`AxisBottom`, `AxisLeft`, `Marks`). React renders the SVG, and D3 v6 handles the data loading and scaling.

Refactored Bar Chart

This example shows the top 10 most populous countries as horizontal bars, with country names on the left axis and population values on the bottom axis. The chart is built with React and D3 v5, using `scaleBand` and `scaleLinear` for positioning, and renders SVG rectangles via the `Marks` component. Data comes from the United Nations World Population Prospects 2019, loaded with `d3.csv`. Axes are drawn using custom components that leverage D3’s tick methods.

Refactored Bar Chart

This example visualizes the top 10 countries by population in 2020 using a horizontal bar chart. The chart displays a linear x-axis for population values and a categorical band scale for country names, with bars rendered as SVG rectangles. Built with React and D3 v6, the code separates concerns into reusable components for axes and marks, and loads data from a CSV file using the `csv` function. The scaleLinear and scaleBand APIs handle the mapping, while React hooks manage the asynchronous data fetching.

Refactored Bar Chart

This example displays a horizontal bar chart of the 2020 populations for the top ten countries, sorted by descending value. Built with React and rendered as SVG, it uses D3’s `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. The custom `AxisBottom`, `AxisLeft`, and `Marks` components draw tick lines, labels, and rectangle bars by mapping data attributes to spatial scales. Population data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV file.
