Four interactive sliders demonstrate d3.svg.brush with a custom cubehelix color scale. Each slider maps a numerical value to a changing fill color via `d3.scale.cubehelix`, creating a rainbow gradient that transitions along the slider track as the brush extent is dragged. The SVG rendering uses rect elements for the slider bar and background, with a Montserrat font for labels. The code is built with D3 3.5.5 and includes a cubehelix interpolation plugin, showing how brush events can drive continuous color updates.

sliders

This visualization demonstrates interactive sliders built with D3.js, where each slider’s filled portion changes color dynamically as the user drags the handle. The sliders use a brush interaction to capture input, and the fill color is mapped through a custom cubehelix color scale (d3.scale.cubehelix) based on the slider’s current value. The SVG rendering includes horizontal and vertical orientations, with text labels and a clean, minimal design. The code also includes an animated transition example, though it is commented out.

sliders

A set of draggable horizontal and vertical range sliders lets a user adjust a value, and each slider’s fill color shifts through a cubehelix color ramp. Built with D3.js version 3.5.5, the sliders use the `d3.svg.brush` API to manage drag interactions, with the brush extent mapped through a linear scale. A separate `cubehelix.min.js` script provides the `d3.scale.cubehelix` color interpolation, which is applied to the slider’s value to produce a smooth, perceptually uniform gradient. The SVG output is rendered directly in the browser, with the slider bars updating live during the drag.

parallel sliders

Parallel sliders presents six horizontal sliders arranged in two rows, each controlling a value from 0 to 100 and displaying a dynamic color fill. The sliders are implemented with D3.js’s `d3.svg.brush` and a custom slider component, using a cubehelix color scale to map slider positions to a rainbow gradient. As a user drags a slider, an `onchange` callback updates the fill color and width, with the SVG animation responding in real time. The code also includes commented-out transitions using `brush.extent` for potential animated value changes.

parallel sliders

A row of five independently draggable sliders uses a cubehelix color scale to fill each bar with a continuous rainbow gradient. As a slider handle moves, its bar dynamically changes length and color, while the fill proportion updates in real time. Built with D3.js and SVG, the custom reusable slider component leverages `d3.svg.brush`, `d3.scale.linear`, and the `cubehelix` interpolation plugin to create smooth, animated interactions.

parallel sliders

This example features a set of draggable sliders that control a parallel-coordinate-style visualization, with each slider’s value mapped to a color using a cubehelix scale. The sliders are implemented with D3’s brush API, and the filled portion of each slider dynamically updates its color and size as the user drags. Built with D3 v3 and SVG, the animation and interactivity respond directly to user input, while the cubehelix color interpolation provides a smooth rainbow gradient across the range.

Brush Slider Test

This example demonstrates a brush-style slider that filters a numeric range, displaying the selected minimum and maximum values as text above the axis. Rendered as SVG, it uses D3 v4’s `d3.brushX()` to create the interactive selection and `d3.brushSelection` to read the current range. The x-axis is generated with `d3.axisBottom` and a linear scale, with the brush initially positioned between 20 and 50 via `brush.move`. The code also notes key API changes from D3 v3 to v4, such as handling brush extents on the brushed element.

This example shows an interactive slider that controls the background color of the page, with a draggable circular handle positioned along a horizontal axis labeled in degrees from 0 to 180. A brushed value updates the hue of the background using `d3.hsl`. The code uses D3 v3’s `d3.svg.brush`, `d3.scale.linear`, and axis components to build the slider, while the `brush` and `brushend` events handle dragging and snap the value to the nearest ten degrees. The rendering is done through SVG elements, with a transition animating the initial brush extent.

Drag Slider

This interactive example demonstrates a slider for selecting a hue value from 0 to 180 degrees, dynamically updating the background color of the SVG canvas. The slider track is overlaid with an invisible, stroke-based capture area that uses the `d3.drag()` API to handle pointer events, converting mouse position to a data value via the inverted linear scale. Tick labels are generated using `x.ticks(10)`, and a white handle with a dark stroke marks the current selection. The visualization opens with a brief, animated transition that uses `d3.interpolate` to smoothly move from 0 to 70 degrees, showcasing the slider’s response.
