Two React components render D3 visualizations side-by-side. A bar chart maps an array of values to SVG rectangles and text labels, using D3's data join with `selectAll`, `enter`, and attribute setters, with colors via HSL strings and classes for high/low values. A second component demonstrates React's managed rendering alongside unmanaged D3 updates, appending HTML elements, merging enter/update selections, and animating appended spans with `transition().duration().delay()`. Both components use `useRef` and `useEffect` to access the DOM, with data generated by `d3.range`.

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.

[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.

D3

This example uses D3 v3 within a React framework to render an SVG visualization on a nearly full-screen canvas. The code sets up a basic HTML page with an SVG element sized to 960 by 500 pixels, demonstrating the integration of D3’s layout and rendering capabilities with React’s component structure. The visualization relies on D3’s data-driven approach, though the specific data or simulation details are not defined in the provided files. The example highlights how SVG elements are manipulated via JavaScript, with CSS controlling page margins and overflow to create a clean, immersive display.

Making a bar chart with React & D3

This example demonstrates how to build a bar chart using React to render SVG elements and D3 to load and parse data. The visualization fetches population data from a CSV file via `d3.csv` and displays it as a series of rectangles, with React’s `useState` and `useEffect` managing the asynchronous data loading. D3 v6 and React 17 are used together, with the chart showing a loading message until the dataset is ready. The SVG-based chart currently renders blank rectangles without positional or size encodings, highlighting the integration of React’s declarative component model with D3’s data utilities.

D3 Learning

This example demonstrates fundamental D3.js data binding and selection techniques through a simple bar chart. It loads an array of numeric values and maps them to SVG rectangles, with the height of each bar proportional to its corresponding data point. The code uses `d3.select` and `d3.selectAll` to manipulate DOM elements, while the `.data()`, `.enter()`, and `.append()` methods create the visual bars from the dataset. Additionally, it shows how to modify text content and styles on headings and paragraphs, illustrating both static selection and dynamic data-driven rendering in React.

React Starter

This example demonstrates a simple D3.js bar chart rendered with SVG inside a React application. The code binds an array of two data values to rectangle elements, setting their width and vertical position based on the data. The chart shows two steelblue bars of different lengths, with the SVG container sized at 800 by 300 pixels. The implementation combines D3 v6’s data join and selection methods with React’s component structure, using standard SVG attributes like `x`, `y`, `width`, and `height` to position the visual elements.

D3 Chart

This example shows a static bar chart built with React and D3.js v4, displaying a simple dataset of nine numeric values as vertical bars. The bars are rendered as SVG rectangles, with heights proportional to the data values and positioned horizontally using a translate transform. The code selects the pre-existing `<svg>` element with the class `bar-chart`, sets its dimensions, and appends rectangles via D3's data join (`enter()` and `append()`). The chart uses `d3.select` and `d3.min` APIs to map values to pixel coordinates.

ICE-6 -Rendering Marks and Channels with React & D3

This example demonstrates how to integrate D3’s data-joining and animation capabilities with React’s component lifecycle to render dynamic bar charts. Using SVG for scalable, resolution-independent graphics, the visualization shows bars that animate in height while displaying numeric labels. The chart leverages D3 v6 scales and axes to map data to positions, with smooth transitions triggered by state changes in React. Marks such as rectangles and text are bound to data via keys, while channels like position, length, and color encode the dataset. The animation uses D3 transitions inside React’s render cycle, highlighting how the two libraries can work together for interactive, web-based visualizations.
