This example shows a horizontal bar chart of the top 10 most populous countries in 2020, using data loaded from a CSV file. D3 scales (scaleBand and scaleLinear) map country names and population values to SVG rectangles, while custom React components (AxisBottom, AxisLeft, and Marks) render the axes and bars. Tick formatting converts large numbers to abbreviated strings (e.g., "1.4B"), and hover tooltips display the formatted population via native SVG `<title>` elements. Styling is applied through CSS classes, with margins and axis labels configured for a clean, readable layout.

Stylized Refactored Bar Chart

This example visualizes the top 10 most populous countries by 2020 estimates using a horizontal bar chart rendered with SVG and React. The chart includes styled axes with tick marks and a labeled "Population" axis, while each bar displays a tooltip with formatted population values (e.g., "1.44B") on hover. The code builds the chart using D3 v5 functions such as `scaleBand` for the categorical y-axis, `scaleLinear` for the numerical x-axis, and `format` for tick labels. Data is loaded asynchronously from a CSV file via `d3.csv` and filtered to the top ten rows.

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.

Refactoring a Bar Chart

This example displays the top 10 most populous countries as a horizontal bar chart, with country names along the y-axis and population values on the x-axis. Built with React and SVG, it uses reusable components to render the bottom axis, left axis, and bars, with scales created via d3.scaleBand and d3.scaleLinear. Data is loaded asynchronously from a 2019 United Nations population CSV using d3.csv, and the visualization responds to loading with a placeholder text.

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 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.

Refactoring bar chart

This bar chart displays the population of the top 10 countries for 2020, using a horizontal layout with country names on the y-axis and population values on the x-axis. It loads CSV data with D3 utilities and renders the visualization with React, creating SVG rect marks for the bars. The code builds custom XAxis and YAxis components from d3 scales (scaleBand, scaleLinear), and uses d3.max to compute the domain. All marks, axes, and labels are rendered as React components, with data fetched asynchronously and displayed after a loading state.

Refactored Bar Chart

This horizontal bar chart displays the population of the top 10 countries in 2020, with country names on the y-axis and population values on the x-axis. Built with React and D3 v7, it uses `scaleBand` and `scaleLinear` to map data to SVG coordinates. The chart is separated into modular components—`AxisBottom`, `AxisLeft`, and `Marks`—each rendering SVG elements like lines and text. Data is loaded asynchronously from a CSV file via `d3.csv`, and all visual elements are rendered declaratively with React's SVG output.

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.
