This example demonstrates D3’s selection and data-join mechanisms by animating a set of circles that move vertically and pulse in radius, connected by a line path. Using `d3.select`, `d3.range`, and `d3.scaleLinear` from the v6 library, the code generates data at 60 frames per second and updates the SVG via `selection.join('circle')` and `selection.join('path')`. The visualization runs in real time, with a smooth sinusoidal motion driven by a timer calling the `vizData` function on the SVG selection.

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 Selection Exploration

This example demonstrates dynamic D3 selection and data binding by animating a set of circles that move and resize in a sine-wave pattern. Using `d3.select`, `selection.data`, and `.join`, it updates the SVG circle positions and radii every frame at 60fps via `setInterval`. The `makeData` function generates the x, y, and r values, while the `vizData` module applies the attributes. Rendering relies on SVG elements with no transitions, showing raw join behavior. The data is synthetic, derived from trigonometric functions, and the visualization fills the browser window.

D3 Selection Exploration V2

This example demonstrates D3’s data-join and selection methods by animating a set of circles that change position and radius over time. The visualization uses `d3.select` to target a container, `selection.data` with a `.join('circle')` pattern to bind and update SVG elements, and a `setInterval` loop to continuously feed new data generated by `scaleLinear` and trigonometric functions. The code relies on D3 v6.6.2’s `selectAll`, `attr`, and `range` APIs, rendering smooth motion without explicit transitions.

D3 selection exploration

This example demonstrates animated selection and data-join techniques in D3, showing fifteen circles bobbing vertically in a sine-wave pattern across the screen. The visualization uses d3.select and d3.range to generate data, then applies the .join('circle') method to bind that data to SVG elements. A setInterval loop running at 60 frames per second updates the circles’ cx and cy attributes, with the y-position calculated from a sine function of the data index and a time variable t. The animation relies entirely on d3 v7’s selection methods and SVG rendering.

D3 selection exploration

This example explores D3 selections and data joins through an animated visualization. A sinusoidal wave of circles moves across the screen, with the number of circles oscillating based on a time variable. The code uses d3.select and d3.range to generate data, then applies the selection’s `.data()`, `.join()`, and attribute setters to update SVG circle positions each frame. The animation runs via `setInterval` at 60fps, with sine functions driving both the vertical placement and count of circles, demonstrating enter, update, and exit behavior.

D3 Selection Exploration

This example demonstrates D3’s data join and selection patterns by animating a row of circles whose count and vertical positions oscillate with a sine wave. The code uses `d3.select`, `d3.range`, and `selectAll().data().join()` to update SVG circles at 60 frames per second, while a commented-out version shows the older `enter()`/`merge()`/`exit()` workflow. The visualization renders directly into the browser window via an SVG element sized to `window.innerWidth` and `window.innerHeight`, with no external data source.

D3 Selection Exploration

A set of animated circles undulates across the screen, their vertical positions and radii oscillating sinusoidally with a slowly changing phase. The visualization demonstrates data joins in D3 v6, using `selectAll`, `data`, and `join` to update SVG circle elements every frame via `setInterval`. Generated data from `makeData` feeds the `vizData` function, which binds new values for `cx`, `cy`, and `r` at 60 frames per second.

D3 Selection Exploration

This example demonstrates the update and join pattern of D3 selections, animating a set of 15 circles and a connecting line path over time. The circles and path are re-rendered every frame using a `setInterval` loop, with their vertical positions and radii driven by a sine function of an incrementing time variable. The code uses `d3.select`, `selection.selectAll`, `selection.join`, and `d3.line` to bind new data arrays generated by `makeData` to SVG elements, showing how D3’s data-join syntax handles dynamic updates efficiently. The visualization runs in a full-window SVG canvas.
