This example is a horizontal bar chart showing the populations of ten countries, derived from the 2020 column of a UN Population dataset loaded as CSV. It displays the data using SVG `<rect>` marks positioned by a d3 scaleBand for countries on the y-axis and a d3 scaleLinear for population on the x-axis, with axes rendered as custom React components. The chart is built with React and d3 v6, separating data loading in a `useData` hook and using functional components like `AxisBottom`, `AxisLeft`, and `Marks` to create a clean, refactored implementation.

Refactored Bar Chart

This example displays a horizontal bar chart showing the 2020 population for ten countries listed in a UN dataset. The chart loads CSV data using the d3 `csv` utility and renders React SVG components for the plot. D3's `scaleBand` and `scaleLinear` are used for the y- and x-axes, respectively, while custom React components (`AxisBottom`, `AxisLeft`, `Marks`) generate the tick marks, labels, and rectangular bars. The visualization is drawn with SVG inside a React application, with the chart area offset by margins defined in the container.

Refactored Bar Chart

This interactive bar chart displays population data for ten countries in 2020, sourced from a UN dataset loaded via d3.csv. The visualization shows horizontal bars ordered by country, with population values mapped to bar width using d3.scaleLinear and d3.scaleBand for positioning. The React component structure separates axis and mark rendering into modular files, with SVG elements generated from scales and mapped data. Custom AxisBottom and AxisLeft components handle ticks and labels, while Marks renders the rectangular bars.

Refactored Bar Chart

This visualization presents a horizontal bar chart comparing the 2020 populations of ten countries, sourced from UN World Population Prospects data on GitHub. Built with React and D3 v7, it renders SVG marks using scales: `scaleBand` positions countries along the y-axis, while `scaleLinear` maps population values to bar widths. The chart explicitly defines reusable components for axes and marks, with `AxisBottom` generating ticks and `AxisLeft` labeling country names, all within a fixed viewport. The data loads asynchronously via `csv`, showcasing a clean, modular refactoring approach.

Refactored Bar Chart

This example shows a horizontal bar chart of population data for the top 10 countries in 2020, using React to render SVG elements. It fetches the UN Population dataset via `d3.csv`, then uses `scaleBand` and `scaleLinear` from D3 v7 to map country names and population values to screen coordinates. The chart is composed of three reusable React components for the bottom axis, left axis, and the bars themselves, with each axis tick and bar generated as separate SVG elements. The visualization demonstrates a modular, component-based approach to building D3 charts within a React framework.

Refactored Bar Chart

This example shows a horizontal bar chart of population data for ten countries, using the United Nations World Population Prospects 2019 dataset. The chart displays each country’s population for 2020 using SVG rectangles scaled by `d3.scaleLinear` and positioned with `d3.scaleBand`. The React components render the axes and marks, with `d3.csv` fetching the dataset and `d3.max` determining the x-axis domain. The visualization highlights a modular refactoring approach where axis and mark components are separated for clarity.

Refactored Bar Chart

This chart displays the 2020 populations of ten countries using horizontal bars, with country names on the y-axis and an x-axis for population values from the UN Population 2019 dataset. The D3 v5 scales `scaleBand` and `scaleLinear` compute the layout, while React components for axes and marks map the data to SVG `<rect>` elements. Population values are parsed from the CSV into numbers via `useData`, and the bars are rendered within an 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 presents a horizontal bar chart of United Nations population data for ten countries, sourced from a CSV file. It shows population values for 2020 using the D3 scale functions `scaleBand` and `scaleLinear` to map countries and populations to SVG coordinates. React components render the marks and axes, with `AxisBottom` drawing tick lines and labels, and `AxisLeft` displaying categorical labels. The chart is built declaratively, avoiding explicit loops, by mapping over scales and data within the component JSX.
