This example visualizes the top 10 most populous countries as a horizontal bar chart, with country names on the y-axis and population values on the x-axis, rendered as SVG via React components. The chart uses `d3.scaleBand` and `d3.scaleLinear` to map data from the United Nations World Population Prospects 2019 dataset. Axis and mark components are split into separate React files, with `Marks.js` drawing rectangles and `AxisBottom` and `AxisLeft` adding ticks and labels, demonstrating a refactored modular architecture.

AI-generated description

A program that shows the top 10 most populous countries as a pathetic bar chart with no axes.

Data: United Nations World Population Prospects 2019.

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.

Refactoring a Bar Chart

This example shows a bar chart of the top 10 most populous countries, with population values from the United Nations World Population Prospects 2019 dataset. The visualization refactors a basic bar chart by adding axes using React components. It uses d3.v5’s `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and renders SVG elements directly through React. The `AxisBottom` and `AxisLeft` components generate tick marks and labels, while the `Marks` component draws the bars.

Refactored Bar Chart

A bar chart from D3 v5 displays the top 10 most populous countries using React primitives, rendering country names and population values as SVG elements. Data comes from the United Nations World Population Prospects 2019. The chart refactors typical D3 components into separate React modules for axes and marks, using `scaleBand` and `scaleLinear` for positioning, with the `Marks` component drawing rectangles.

Refactor bar chart

This example displays a horizontal bar chart of population data for the top 10 countries from a UN 2019 dataset, rendered as SVG elements within a React component. The code uses d3-scale's `scaleBand` and `scaleLinear` to map country names and population values to screen coordinates, while `AxisBottom` and `AxisLeft` generate the tick marks and labels using D3's tick system. Bars are drawn as `rect` elements via the `Marks` component, with width proportional to each country's population. Data is fetched asynchronously using the `csv` function from D3 v6.

Refactored Bar Chart

This example displays the top 10 most populous countries as horizontal bars, ranked by population, with country names on the left and a linear population scale on the bottom. Built with React and D3 v5, it uses `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and renders SVG rectangles via the `Marks` component. Axis labels and ticks are generated by `AxisBottom` and `AxisLeft`, which map scales to SVG elements. Data comes from the UN World Population Prospects 2019 CSV, loaded asynchronously with `d3.csv` inside a custom `useData` hook.

Refactored Bar Chart

This example displays the population of the top ten countries from the UN Population 2019 dataset as a horizontal bar chart. React components render the SVG marks and axes, while D3 utilities handle the data loading and scale calculations. The chart uses a `scaleBand` for the categorical y-axis, a `scaleLinear` for the quantitative x-axis, and `csv` for fetching the data. Each component (`AxisBottom`, `AxisLeft`, `Marks`) is modularized and receives the scales and data via props, highlighting a reusable and refactored architecture for visualization.

Refactored Bar Chart

This example presents the top 10 most populous countries as a horizontal bar chart, with country names on the y-axis and population values on the x-axis, sourced from the United Nations World Population Prospects 2019. The visualization is built with React and D3 v5, using `scaleBand` and `scaleLinear` to position bars and axes, while SVG `<rect>` elements render the marks. The code separates concerns into reusable components for the bottom axis, left axis, and marks, and loads data asynchronously via D3’s `csv` parser.

Refactor Bar chart

This bar chart visualizes the population of the top 10 countries in 2020, using horizontally-oriented bars. Built with React and SVG, the example decomposes the visualization into reusable components: `AxisBottom`, `AxisLeft`, and `Marks`. It uses `d3.scaleBand` for the categorical y-axis, `d3.scaleLinear` for the population x-axis, and `d3.max` for domain calculation. Data is loaded asynchronously from a CSV file via a custom `useData` hook, which fetches and parses the UN Population 2019 dataset.
