This example presents a horizontal bar chart displaying population data for the top 10 countries from a UN 2019 dataset. Using D3.js v7 for scales and SVG rendering within a React component, the chart separates axis and mark rendering into modular functions. The bottom axis shows linear population values, while the left axis displays categorical country names using a band scale. React's useState hook manages the asynchronously loaded CSV data, which is parsed and sliced before being converted into rectangular SVG elements via the Marks component.

AI-generated description

A program that loads in some data about CSS named colors using d3 utilities, and uses React state to keep track of the data.

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 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 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.

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 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 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 example shows a horizontal bar chart of UN population data for 2019, displaying the top 10 countries by population. The chart uses React components to render SVG bars and axes, with D3 utilities like `scaleBand` and `scaleLinear` for positioning and scaling. Data is loaded asynchronously via D3’s `csv` parser, and React’s `useState` and `useEffect` hooks manage the data fetching and state. The axes and marks are separated into reusable React components, demonstrating a modular approach to building visualizations.

Refactored Barchart

This horizontal bar chart displays the populations of the top 10 countries from the UN Population 2019 dataset, sorted by country name. Built with React and D3 v5, it uses `scaleBand` for the y-axis and `scaleLinear` for the x-axis, rendering bars as SVG `rect` elements. The chart loads the data via `d3.csv`, and both the left and bottom axes are rendered as separate React components (`AxisLeft`, `AxisBottom`), with marks generated by the `Marks` component.
