Using React hooks and D3 v5, this visualization displays the top 10 countries by 2020 population as a horizontal bar chart. The SVG rendering uses `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and custom React components (`AxisBottom`, `AxisLeft`, `Marks`) that call D3-axis ticks and scale methods. Data is loaded from a CSV via the `csv` promise API in `useData.js`.

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 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 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.

Refactored Bar Chart

This bar chart displays the top ten countries by population for 2020, using horizontal bars sorted by country name. The visualization is built with React for component rendering and D3 v7 utilities for data loading and scales, including `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Data is fetched via D3’s `csv` parser from a GitHub gist, with SVG elements composed from reusable React components like `AxisBottom`, `AxisLeft`, and `Marks`.

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 presents a horizontal bar chart that ranks the top ten countries by their 2020 population. It demonstrates how D3’s scale functions and React state can be combined to build a clean, interactive visualization. The chart uses a band scale for the categorical y-axis and a linear scale for the continuous x-axis. Axis tick marks and labels are generated with custom React components, while bars are drawn as SVG rectangles. Data is loaded from a remote CSV file using the D3 `csv` method and managed through React’s `useState` and `useEffect` hooks.

Refactored Bar Chart

This visualization shows the population of the top 10 countries in 2020 as a horizontal bar chart, with all bars aligned to the left and sorted by country name. The application loads the data from a CSV file using D3’s `csv` utility, then renders the SVG with React components for the axes and marks. The y-axis uses `scaleBand` to position categorical labels, while the x-axis uses `scaleLinear` for the numeric population values. Each bar is drawn as a `<rect>` via the `Marks` component, with size determined by the population value.

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.
