This example demonstrates a dynamic line chart created with D3, where 15 points oscillate vertically over time based on a sine function. The visualization uses D3's `select` and `range` APIs to build an SVG canvas and animate both circles and a connected path. Using D3's `.join()` method, the code efficiently updates element attributes on each frame, with a `setInterval` timer driving the animation at 20ms intervals. The implementation uses the React framework and renders purely through SVG elements, with the data generated procedurally from a mathematical function rather than external sources.

D3 Selection Exploration

This example presents an animated scatter plot and line chart driven by a sinusoidal wave. A set of circles and a connecting path update 60 times per second, with the number of points oscillating between five and fifteen and their vertical positions shifting over time. Built with React and D3.js, the code uses `d3.select`, `selectAll`, and `join` to bind data to SVG elements, while `d3.range` generates the sequence and `d3.lineGenerator` computes the path’s geometry. All rendering occurs in SVG with smooth, real-time animation.

D3 Selection exploration

This example demonstrates how D3 selections manage dynamic data updates through animation. An SVG scene continuously redraws a set of circles and connecting lines, with the number of elements oscillating between 5 and 15 based on a sine wave. The code uses D3’s `select` and `range` functions, along with the `join` pattern to bind data to circle and line elements. Data is generated procedurally via `makeData`, updating positions and radii each frame. React serves as the framework wrapper, while the animation runs on a `setInterval` timer with a 60fps approximation.

D3 Selection Exploration

This example demonstrates how D3’s data join pattern animates a dynamic set of circles, whose count and vertical positions oscillate sinusoidally over time. Using `d3.select` and `d3.range`, it generates an array of points and binds them to SVG circle elements via `selection.data()` and `selection.join()`, updating `cx` and `cy` attributes each frame. The code runs a `setInterval` at 60fps, recalculating data with a time-based sine wave, while `d3` version 7.6.1 manages enter, update, and exit states automatically.

D3 Selection exploration

This example demonstrates D3 selection and data-join patterns by animating a series of circles and connecting lines across a full-screen SVG. As time progresses, the circles oscillate vertically along sine waves while lines link consecutive points. The code uses `d3.select`, `d3.range`, and the `selection.join` method to bind and update elements each frame. Rendering is driven by a `setInterval` loop that regenerates the data and re-applies the `makeCircle` and `makeLine` functions, highlighting how D3 manages enter, update, and exit states.

D3 Selections

This example animates a set of circles and vertical lines in an SVG, with the circles bobbing up and down in a sine wave pattern over time. The visualization uses D3’s `select`, `append`, and `selectAll` APIs to manage the SVG elements, and the `join` method to update the DOM as new data arrays are generated each frame by `makeData`. The animation is driven by a `setInterval` timer that updates the data and redraws the scene at 60 frames per second, with line opacity varying based on the circle’s vertical position.

D3 Selections

Two hundred blue circles form a sine wave that continuously animates across the screen, with each circle’s vertical position shifting based on a time-driven formula. The visualization demonstrates D3’s data join pattern using `selectAll`, `data`, and the `.join()` API to efficiently update existing SVG circle elements rather than recreating them. The example runs in a React framework with SVG rendering, updating every 16 milliseconds via a JavaScript `setInterval` timer, and pulls data from a procedurally generated range of 200 points.

d3 Slection

This example demonstrates a dynamic scatter plot of animated circles whose vertical positions oscillate sinusoidally over time. It uses React and the D3.js v7 library, specifically `select`, `range`, `data`, and the `join` API to create and update SVG circles each frame. The visualization runs on a 60Hz interval, recomputing data with the sine of a time variable to produce smooth, continuous motion across the screen.

Exercise for D3 Selection Exploration

This example is an exercise in using D3.js selection and join operations to create an animated visualization. It shows a dynamic set of 15 circles moving vertically in a sine wave pattern, with black vertical lines extending from each point and a polyline connecting them all. The animation updates at 60 frames per second using `setInterval`, and the positions are calculated with `Math.sin` in the `makeData` function. The code uses D3's `select`, `range`, and `line` functions, along with the `.join()` method to efficiently add or update SVG circles and path elements.
