This example shows a horizontal bar chart of the top 10 countries by population in 2020, loading data from a CSV file and rendering it as SVG in a React app. The chart uses React function components for modular pieces: `Marks` renders rectangles using a band scale for countries and a linear scale for population, while `AxisBottom` and `AxisLeft` generate tick marks and labels. The code leverages D3 v5 utilities like `scaleBand`, `scaleLinear`, `max`, and `csv`, with React hooks (`useState`, `useEffect`) managing data fetching via the custom `useData` hook.

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 displays a horizontal bar chart of the top ten countries by population in 2021, using a linear scale for bar lengths and a band scale for row positions. It loads data from a CSV file via D3’s `csv` utility, then renders SVG rectangles and custom axis components built with React. The `AxisBottom` and `AxisLeft` components create tick marks and labels, while the `Marks` component maps each data row to a `rect` element. React’s state management, via `useState` and `useEffect`, handles asynchronous data loading.

Fork of Refactored Bar Chart

This example visualizes the top 10 most populous countries as horizontal bars, using SVG rendering within a React app. The chart displays population values against country names, with no axes initially, though it includes bottom and left axis components built from D3 scales. Data comes from the UN World Population Prospects 2019 CSV, loaded via `d3.csv`. The code uses React hooks (`useState`, `useEffect`) and D3 v5 functions like `scaleBand` and `scaleLinear` to position marks and axes, with all rendering handled by React elements.

Fork of Refactored Bar Chart

This example visualizes the top 10 most populous countries using horizontal bars, with the country names on the y-axis and population values mapped to bar lengths along the x-axis. The chart is rendered as SVG using React, with D3’s `scaleBand` and `scaleLinear` handling the axes and scaling. Custom React components (`AxisBottom`, `AxisLeft`, `Marks`) generate the tick marks and rectangles, while D3’s `csv` loads data from the United Nations World Population Prospects 2019 dataset. The chart includes axes with tick labels, improving readability over a bare bar display.

Fork of Refactored Bar Chart

This example displays the top 10 most populous countries as horizontal bars, using React for component structure and D3 v5 for scales and data loading. The chart renders as SVG, with `d3.scaleBand` positioning categorical country labels on the y-axis and `d3.scaleLinear` mapping population values to bar widths. Axis components (`AxisBottom`, `AxisLeft`) draw tick marks and labels from the scales, while `Marks` generates each rectangle. Data comes from the United Nations World Population Prospects 2019 CSV, loaded asynchronously with D3’s `csv` function.

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 a horizontal bar chart of the top ten countries by population in 2020, fetched from a CSV file via `d3.csv` and rendered as SVG using React. The chart employs `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. A bottom axis renders grid lines and tick labels, while a left axis displays country names. Refactored into separate components (`AxisBottom`, `AxisLeft`, `Marks`), it demonstrates a modular approach to building interactive data visualizations with React and D3 v5.

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.
