This example displays a horizontal bar chart of the top 10 countries by population in 2020, according to UN data loaded from a CSV file. Built with React and D3 v7, the chart is rendered as SVG. The code constructs the visualization using modular components, with `AxisBottom` generating the quantitative scale ticks, `AxisLeft` labeling the categorical country names, and `Marks` drawing the bars. The `useData` hook fetches the data, while `scaleBand` and `scaleLinear` handle the layout.

Ep. 23 | Refactored Bar Chart

This example displays a horizontal bar chart of the top 10 countries by population from the United Nations World Population Prospects 2019 dataset. Rendered as SVG using React components, the chart uses d3.scaleBand and d3.scaleLinear for positioning, with custom AxisBottom, AxisLeft, and Marks components. The code demonstrates a refactored pattern where D3 is used for scales and data processing while React handles the DOM rendering, with d3.csv loading the data asynchronously via a useData hook.

Refactored Bar Chart

This example visualizes the population of the top 10 countries from UN Population 2019 data as a horizontal bar chart. The chart uses D3 scales (`scaleBand` and `scaleLinear`) to position bars and axes, while React components render the SVG elements. The code separates AxisBottom, AxisLeft, and Marks into distinct React components, uses a custom `useData` hook to load and parse the CSV with d3.csv, and supports blank ticks as axis labels. The visualization highlights a modular, refactored approach to building reusable chart components.

Refactored Bar Chart

This example presents a horizontal bar chart of the top ten countries by 2020 population, sourced from a UN population dataset. It demonstrates a modular code organization using React components for the bottom axis, left axis, and the rectangular marks, each rendered with SVG. The chart specifically uses D3's `scaleBand` and `scaleLinear` to map the data to pixel coordinates, while the React `useData` hook fetches and parses the CSV file. The bars are scaled proportionally to each country's population value.

Refactored Bar Chart

This visualization displays a horizontal bar chart of the top 10 countries by population in 2020, using data loaded from a CSV file of UN population estimates. The example demonstrates how to structure a React-based D3 chart with clearly separated axis and mark components, with margins applied to position the left and bottom axes. It uses D3 v7’s scaleBand and scaleLinear for scales, react-fragments to render SVG groups, and a custom useData hook with d3.csv for data fetching. The chart highlights the importance of margin configuration for effective axis placement.

Refactored Bar Chart

A horizontal bar chart displays the top 10 countries by population for 2020, using UN population data loaded via D3's `csv` utility. The React app renders SVG rectangles through the `Marks` component, with scales from `d3.scaleBand` and `d3.scaleLinear` positioning bars and axes. Reusable `AxisBottom` and `AxisLeft` components generate tick marks and labels. The chart is built with React 16.9, D3 v7, and SVG rendering, isolating data-loading logic in a custom `useData` hook.

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 example shows a horizontal bar chart of the top 10 most populous countries in 2020, using data loaded from a CSV of UN population estimates. The visualization is built with React components that render SVG elements, with D3 v7 providing the scale functions (`scaleBand`, `scaleLinear`) and the `csv` data loader. Separate React components handle the axes and marks, with the bottom axis using `xScale.ticks()` to generate tick values and the bars sized via the `xScale` and `yScale` outputs.

Refactored Bar Chart

This example shows a horizontal bar chart of the top ten countries by population in 2020, using UN Population data. The visualization is built with React and D3 v6, where D3 utilities like `scaleBand` and `scaleLinear` compute the chart scales. The code refactors the visualization into modular components, with separate files for the axes (`AxisBottom`, `AxisLeft`) and the bars (`Marks`), demonstrating a clean separation of concerns. The chart is rendered as SVG, and the data is loaded asynchronously using the `csv` function from D3.
