This example demonstrates how to combine React Hooks with D3 to render and update a simple SVG scatterplot. A `useState` hook manages an array of numeric data, while a `useRef` hook and `useEffect` hook initialize an SVG canvas using `d3.select` from D3 v5. Circles are appended via `selectAll(...).data(...).join('circle')`, with radius and position derived from each value. Clicking the “Update” button increments the data by 5, and “Filter” removes values over 35, triggering a re-render through React’s state changes.

Basic React Hook Test (Circles - Fixed Data)

This example demonstrates how React hooks can manage D3-driven SVG circle updates with fixed data. The app initializes an array of seven values, rendering each as a grey circle with a blue stroke, positioned via attributes calculated from the data. Two buttons trigger state changes: “Update Data” adds five to every value, while “Filter Data” removes values above 35, causing D3’s join method to add, remove, or update circles accordingly. The code uses the `useRef`, `useState`, and `useEffect` hooks, alongside `d3.select` and `.join()`, with React 16.12 and D3 v5.

[03] Axes and scales - Using React Hooks with D3

This example shows a line chart of an array of numeric values rendered as a smooth, cardinal-curved path with labeled axes. The code uses React Hooks with `useState` and `useRef` to manage data and the SVG element, while D3 v5’s `scaleLinear`, `axisBottom`, `axisRight`, and `line` with `curveCardinal` construct the visualization. Buttons update or filter the data, triggering a re-render that redraws the line and axes against a fixed 900×400 SVG viewport.

[05] Interactivity - Using React Hooks with D3

This interactive bar chart demonstrates how React hooks and D3 v5 work together to create a dynamic, animated visualization. The example uses `useState` and `useEffect` to manage a mutable data array, while D3's `scaleBand`, `scaleLinear`, and `join` method handle the rendering of SVG bars and tooltips. On mouseenter, a tooltip text element appears with data binding, positioned using the band scale’s index value, and animates its opacity and y-position via `transition()`. Buttons trigger data updates—increment, decrement, filter, or append—which re-render the chart through the React state change. The code also demonstrates axis generation with `axisBottom` and `axisRight`, applying a color scale to bar fills based on value.

[02] Curved Line Chart - Using React Hooks with D3

This example demonstrates a curved line chart rendered as an SVG, where a dataset of numeric values is mapped to a path using D3’s `line` generator with the `curveCardinal` interpolation. The chart initializes with twenty points, and two buttons trigger updates: one increases every value by 5, while the other filters out values below 35, causing the line to redraw dynamically. React hooks (`useRef`, `useEffect`, `useState`) manage the SVG element and data state, while D3’s `select` and `path` joins handle the visual update. The viewport is set to 940 by 450 pixels, with a yellow fill and blue stroke.

D3 and React Hooks

Two pie charts render identical datasets side by side, each taking a different approach to integrating D3 with React function components. The first, PieSVG, lets React fully manage the SVG lifecycle, mapping data arcs to JSX elements. The second, PieHooks, uses `useEffect` and `useRef` to imperatively manipulate the DOM with D3 selections like `selectAll`, `enter`, and `merge`. Both use `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate and style the arcs, with random data regenerated on button click.

Circles with D3 and React

This example renders a scatterplot of 14 colored circles on an SVG canvas using React and D3. Each circle’s position, radius, and color come from static data defined in a separate JavaScript module. The visualization integrates React’s `useRef` and `useEffect` hooks with D3’s `select` method to bind data and create circle elements via `join`. The D3 v7 code applies `attr` setters for cx, cy, r, and fill properties.

Loading Data with React and D3

This example demonstrates how to load data with D3 utilities and manage it through React state. The application uses React’s `useState` hook to store data that has been fetched, while D3’s `d3.min.js` library is included for data processing and visualization utilities. The rendering is done as an SVG element, with a commented-out example showing multiple circles that could be displayed. The React DOM renders the main component into the HTML root element, and the data is initially set to `null` before being populated.

D3 + React + useData

This example demonstrates how to build a D3.js visualization within a React application using a custom `useData` hook to load CSV data from a GitHub gist. It shows a set of circles whose count and size are dynamically controlled by input fields. The code combines React's `useRef`, `useState`, `useMemo`, and `useCallback` with D3's `select` API for incremental updates, and uses a `VizContainer` component to structure the SVG with margin conventions.
