This visualization presents a horizontal bar chart of the ten most populous countries in 2020, using data from the UN Population dataset. It showcases a refactoring pattern where D3’s scale functions and tick generation are used within React components to render SVG elements. The code demonstrates using `d3.scaleBand` and `d3.scaleLinear` for axes and bar positioning, while custom React components like `AxisBottom`, `AxisLeft`, and `Marks` encapsulate SVG line, text, and rect elements. The rendering is pure SVG, dynamically generated from a CSV file via `d3.csv`.

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

A horizontal bar chart displays the top ten most populous countries for 2020, based on UN population data loaded via `d3.csv`. Using React and SVG within a D3 v5 framework, the visualization separates concerns by organizing reusable components for rendering axes and marks. The chart applies `d3.scaleBand` for country categories on the y-axis and `d3.scaleLinear` for population on the x-axis, with the bottom axis presenting population values and left axis showing country names.

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 is a bar chart ranking the ten most populous countries according to UN 2019 population data. The visualization uses React to manage component state and rendering, while D3 v6 utilities like `scaleBand` and `scaleLinear` handle the scales and axes. The chart is rendered as an SVG, with data loaded asynchronously from a CSV via `csv`. The code defines reusable React components for the bottom and left axes and the bar marks, showcasing a modular, refactored approach to building D3 visualizations within a React framework.

Refactored bar chart with React & D3

This example shows a horizontal bar chart ranking the 15 most populous countries based on UN Population data from 2019. The visualization uses React components to render SVG elements, with D3 scales handling the positioning. The code separates axis and mark rendering into distinct functional components, using `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the numeric x-axis. Data is loaded asynchronously via a custom `useData` hook that fetches and parses the CSV dataset.

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 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 presents a horizontal bar chart displaying the top 10 most populous countries for the year 2020, sourced via a CSV from the UN Population dataset. Built with React and D3 v5, it uses D3’s `scaleBand` and `scaleLinear` to compute scaling and relies on custom components for axes and marks. The chart renders as an SVG through React components, with D3’s `csv` utility fetching and parsing the data.
