This example displays a horizontal bar chart of population figures for the top 10 countries, sourced from a UN Population 2020 CSV file. Built with React and D3 v6, it uses `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. The SVG rendering is composed from reusable components: `AxisBottom` generates tick lines and labels, `AxisLeft` places country names, and `Marks` draws the rectangles. Data is loaded asynchronously via `useData` and `d3.csv`.

Refactored Bar Chart

This chart displays population data for the top 10 countries in 2020 using horizontal bars, with country names on the y-axis and population values on the x-axis. Built with React and D3 v6, the visualization uses D3's `scaleBand` and `scaleLinear` for axes, `format` for tick labels, and SVG elements for rendering. Data is loaded asynchronously via D3's `csv` function from a UN Population dataset. A tooltip reveals the exact population value for each bar.

Refactored Bar Chart

This example presents a horizontal bar chart of the top 10 countries by population for 2020, sourced from a UN population CSV file. The visualization uses React with D3 v5 utilities to load and scale the data, rendering SVG via React components. `scaleBand` positions country labels on the y-axis, while `scaleLinear` maps population values to bar widths, with reusable `AxisBottom`, `AxisLeft`, and `Marks` components structuring the chart.

Refactored Bar Chart

This visualization shows the top 10 countries by population for 2020 as a horizontal bar chart, with country names on the y-axis and population along the x-axis. Loading data via d3.csv from a UN population CSV, it uses React components to render SVG rects, with scales built from d3.scaleBand and d3.scaleLinear. Axis ticks and labels are generated manually with React JSX, mimicking D3’s axis pattern without d3.axisBottom or d3.axisLeft.

Refactored Bar Chart

This example shows a horizontal bar chart of the top 10 countries by 2020 population, as listed in the UN Population 2019 CSV dataset loaded via D3’s `csv` utility. The React component uses `scaleBand` and `scaleLinear` to map country names and population values to the SVG viewport, with the bars rendered as `<rect>` elements in `Marks.js`. The axis components `AxisBottom` and `AxisLeft` reuse D3’s scale functions directly, while React state managed by `useState` and `useEffect` handles asynchronous data loading.

Refactored Bar Chart

This example shows a horizontal bar chart of the top 10 countries by 2020 population, using data loaded from a CSV of UN population figures. The chart renders bars with SVG `<rect>` elements, with a linear scale for the x-axis and a band scale for the y-axis. React components structure the visualization, while D3 utilities like `csv`, `scaleBand`, and `scaleLinear` handle data loading and scaling. Axis components generate tick marks and labels, all within a fixed-width SVG canvas.

Refactored Bar Chart

This example shows a horizontal bar chart of the top ten countries by 2020 population, sourced from a CSV file of UN population data. The chart uses React components to render the visualization as SVG, with d3-scale for the `scaleBand` y-axis and `scaleLinear` x-axis positioning. Population values drive bar widths, while country names label the left axis. The code is refactored into separate, reusable components for the axes and marks, with data loading handled by a custom `useData` hook that uses d3.csv.

Refactored bar chart

This example shows a horizontal bar chart displaying the top 10 countries by population for 2020, using data from a UN Population CSV file. It demonstrates a modular React component structure with separate files for axes, marks, and data loading. The chart renders as SVG using React elements, with a d3.scaleBand for the categorical y-axis and d3.scaleLinear for the quantitative x-axis. The code uses d3.csv for data fetching and parsing, and d3.max to compute the population domain.

Refactored Bar Chart

This example presents a horizontal bar chart showing the population of the top 10 countries from a UN Population dataset. The chart uses React components to render SVG elements, with D3’s `scaleBand` for the categorical country axis and `scaleLinear` for the numeric population axis. The visualization is split into modular components, including `AxisBottom`, `AxisLeft`, and `Marks`, which draw the ticks and rectangles. Data is loaded asynchronously via `d3.csv`, and the chart updates upon data arrival.
