Input Value Interpolation

Input Value Interpolation

This example animates the value of an HTML range input from 0 to 255 over 7.5 seconds, visually demonstrating how a transition can interpolate a DOM property. It uses a custom `valueTween` function that returns a closure over `d3.interpolateNumber`, which computes the numeric interpolation between the input’s current value and the target. The transition, chained via `d3.select("input").transition()`, applies this tween to the `value` attribute, updating the slider’s position in real time. The page includes no external data, relying solely on D3 v3’s transition and tween APIs.

Range Transition

A single range input animates from 0 to 1000 over 7.5 seconds, demonstrating a custom property transition. Using D3 v3, the code selects the input element and applies a transition with a duration, then uses `transition.tween` to interpolate the `value` attribute via `d3.interpolate(this.value, this.max)`. Each animation frame updates the input’s value, producing a smooth numeric slide. The example shows how to tween arbitrary DOM properties not covered by standard D3 transitions.

D3 Transitions - Custom Tweens

The example showcases circular transitions of data-driven points using D3.js, contrasting a default linear interpolation with a custom tween that animates along the shortest angular path. Two SVG canvases display circles that jump between random angles on a fixed radius. The left pane uses standard `transition().attr` calls, while the right pane employs a custom `transition().tween()` with D3's `interpolate` to handle angle wrapping and ensure smooth, direct movement across the circumference. The code updates the data on button click, demonstrating the API's flexibility for controlling animation behavior.

Input test

This interactive example demonstrates how an HTML range slider controls the rotation of two text labels. Dragging the slider changes the angle of "d3.js" text while simultaneously rotating "d3noob.org" in the opposite direction. The visualization uses D3 v4 to select the SVG elements and bind the input event to the update function, which modifies the rotate transform property of each text element. The page relies on D3's selection API (`d3.select`) and property accessor methods to synchronize the slider value with the displayed angle.

d3-simple-slider

This example demonstrates a variety of interactive slider configurations using the d3-simple-slider library, built on D3 v5. It showcases simple, stepped, time-based, filled, ranged, and vertical sliders, along with alternative handles and transitions, with each slider updating a displayed value. The page includes extended examples inspired by a New York Times article and a color picker, all rendered as SVG elements within a Bootstrap layout. The sliders are created using `d3.sliderBottom` and `d3.sliderTop` APIs, with options for tick formatting, step values, and fill colors, and respond to user input via the `onchange` event.

Input test

This example demonstrates how an HTML range slider can control the rotation of a text element rendered as SVG. The display shows the text “d3noob.org” centered on a 600 by 300 canvas, with its angle dynamically updated as the slider moves. Built with d3.js v4, the code uses d3.select to bind input events, update the displayed angle value, and apply rotation via the transform attribute’s rotate() function. The initial state is set to zero degrees, and the slider’s range spans from 0 to 360 degrees.

Input test

This example uses an HTML range input slider to interactively rotate two text labels in an SVG scene. Dragging the slider changes the angle value, which is applied to rotate the "d3.js" and "d3noob.org" texts in opposite directions using `d3.select` and the `.on("input")` event. The SVG elements are updated by setting their `transform` attributes with the rotation angle, while the input’s value and label are synchronized through `d3.select` and `.property()`. The visualization demonstrates basic event handling and attribute binding with d3.js v6.

Input test

This example demonstrates how an HTML range input slider controls the rotation of an SVG text element in D3.js v6. The text "d3noob.org" is initially centered and rotated to 0 degrees, then updates its angle in real time as the user drags the slider from 0 to 360. The code selects the range input with `d3.select("#nAngle")` and listens for the `input` event to trigger an `update` function, which dynamically modifies the `transform` attribute of the text element. Rendering is done via SVG appended to the body with D3's selection and attribute methods.
