World map with React & D3

This example displays a world map rendered as an SVG using React and D3 v5. The map shows country boundaries and a background sphere, styled with a teal fill and light gray strokes. It loads geographic data from a TopoJSON file via the `world-atlas` package, converting it to GeoJSON with topojson’s `feature` function. The projection and path generation rely on `d3.geoEqualEarth` and `d3.geoPath`, while React components manage the rendering and data loading through a custom `useData` hook.

Stylised Line Chart with React & D3

This stylized line chart visualizes San Francisco temperature readings over a week, using a natural curve to connect data points and circular markers with hover tooltips. Built with React and D3 v5, it renders as an SVG, mapping timestamps to the x-axis via `d3.scaleLinear` and formatting tick labels with `d3.timeFormat`. The chart leverages `d3.line` with the `curveNatural` option for smooth paths, while custom axis components handle gridlines and labels. Data is loaded asynchronously from a CSV using `d3.csv`. The clean, minimalist design uses the Poppins font and a teal accent color.

Stylized Scater Chart with React & D3

This example shows a stylized scatter plot of the Iris dataset, plotting sepal length against sepal width. Each flower is rendered as a teal circle with a tooltip showing the sepal length value. The visualization is built with React components that generate SVG elements, using D3 v5’s `scaleLinear` for scales and `extent` for domains. Axes are custom components that render tick lines and labels, with an `.2s` format applied to tick values. The data is loaded asynchronously via D3’s `csv` function and mapped to numeric fields.

Styled Bar Chart woth React & D3

This example shows a horizontal bar chart of the top 10 countries by population in 2020, with each bar labeled with its country name and a formatted x-axis displaying population in billions. The React components `Marks`, `AxisBottom`, and `AxisLeft` render SVG rectangles and tick marks, while the custom `useData` hook fetches the CSV via `d3.csv` from a GitHub gist. Styling uses CSS classes with the Poppins font, and D3’s `scaleBand` and `scaleLinear` handle the coordinate mappings, with `d3.format` applied to abbreviate tick labels.

Fork of Refactor Bar Chart woth React & D3

This visualization presents a horizontal bar chart of the ten most populous countries, sourced from the UN’s 2019 population dataset, using React to manage the component structure and D3’s `scaleBand` and `scaleLinear` to compute the layout. The code renders bars as raw SVG `<rect>` elements, with axes generated as SVG `<line>` and `<text>` elements via custom `AxisBottom` and `AxisLeft` components. Data loading is handled through a custom `useData` hook that fetches and parses the remote CSV file with D3’s `csv` function.

The Margin convention

This example demonstrates the margin convention in D3.js by rendering a bar chart of United Nations population data for 2019, showing the top 10 countries. The visualization uses React components with D3 scales (d3.scaleBand and d3.scaleLinear) to map countries to the y-axis and population values to the x-axis. An SVG group element applies the margin offsets via a transform, separating the plotting area from the axes. The code fetches the CSV data using d3.csv and renders grid lines, tick labels, and horizontal bars within the defined inner dimensions.

Pathatic bar chart with React & D3

This visualization displays a horizontal bar chart comparing the population figures of the top ten countries from a UN Population dataset for 2020. The example uses React with the D3.js library to load and process the data, and renders the final chart as SVG elements through React's declarative component model. The chart employs D3's `scaleBand` for the categorical y-axis positioning of countries and `scaleLinear` for the numerical x-axis representing population size.

Circle follow the Mouse React and SVG.

A yellow circle follows the mouse cursor across a full-window React SVG canvas. The circle’s position updates continuously via React’s `useState` and `useCallback` hooks, triggered by the SVG’s `onMouseMove` event. The code uses `window.innerWidth` and `window.innerHeight` to size the canvas, and ReactDOM renders the interactive component. This demonstrates real-time state-driven rendering with React and SVG.

Fork of Smiley Face Part V

This example shows a grid of randomly generated smiley faces, each with different eye positions, mouth widths, and stroke thicknesses. Built with React and D3 v5, the code splits face components into separate ES6 modules (Face, Eyes, Mouth, FaceContainer) and uses React Fragments to group elements. D3’s arc generator creates the mouth path, while a range from d3 generates the array of faces, each rendered as SVG with randomized parameters.

[SB] React Smily Face

This example renders a stylized smiley face as a scalable vector graphic using React components for the face, background circle, eyes, and mouth. The mouth is drawn with a D3 arc generator, while the face’s dimensions and features are configured through props. The visualization demonstrates composition of React elements within an SVG container, using D3 v7 for the arc path and React 18 for rendering.
