This example shows an interactive range slider built with D3 v4, where a user can brush along a band scale to select a subset of values from a fixed array of numbers 1 through 10. The visualization displays the current selection as an orange arrow and a label showing the selected range. The slider includes adjustable step size, slider size, and initial index via HTML inputs, with an "Apply" button to update the scale dynamically. The code relies on `d3.scaleBand`, `d3.brushX`, and SVG element manipulation to compute snapped positions and render the selection handle.

D3 range selecter

This example shows an interactive range selector built with D3 v7, displayed as a horizontal slider with two triangular drag handles positioned over an axis. Users adjust the left and right handles to select a numeric interval between a minimum of 34 and a maximum of 100, with the current range logged to the console on release. The visualization renders in SVG and uses d3.scaleLinear, d3.axisBottom, d3.drag, and d3.symbolTriangle to manage the scale, ticks, and handle movement. The handles are constrained so they cannot cross, and their positions are recalculated using scale inversion.

Range Slider

This example presents a range slider visualization that lets users drag a handle to select a numeric value between 0 and 100. A large circular dragger and a triangular pointer both respond to mouse drags, with a label updating to show the current percentage. The implementation uses the d3-marcon library for layout, along with d3-scaleLinear for mapping data values to pixel coordinates, d3-drag for interactive dragging, and d3-axisBottom for rendering the scale. The slider’s body, axis, and dragger are styled via CSS classes.

D3 sliders

This example shows an interactive bar chart of a small dataset where dragging a vertical HTML range slider recolors bars below a threshold value from light blue to dark blue. The chart uses D3 version 7 scales (`scaleBand` and `scaleLinear`) to position and size SVG rectangles, and React is mentioned as the framework context. The slider’s `change` event triggers a D3 transition over 500 milliseconds to animate the fill color change, demonstrating linked interaction between an HTML input and D3-managed SVG elements.

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.

Slider test 1

A range slider, built with the d3-simple-slider library, selects an interval on a horizontal axis. The slider’s default value is set between 0.015 and 0.02, and its current selection is displayed as a formatted percentage range in a paragraph. A D3 v6 SVG visualization renders the control, with the slider’s fill color set to blue. The underlying data, drawn from a CSV file, is not used in the interaction.

Color Range slider

This example demonstrates an interactive color range slider that dynamically adjusts the displayed hue. Users manipulate the slider to select a specific color value, which updates the visualization in real time. The implementation uses React for component state and rendering, while D3.js (d3.v5) manages the slider’s input handling and color scale transitions. The project references the React Starter template and uses a minimal HTML page with embedded D3 and custom CSS for styling. The color transitions are driven via D3’s interpolation methods, though the exact rendering target is not specified beyond the slider interaction.

Drag Slider

This slider example demonstrates interactive color selection by dragging a circular handle along a horizontal track. The handle position maps linearly to hue values from 0 to 180 degrees, updating the SVG background color in real time. Built with D3 v4, it uses `d3.drag` for pointer interaction and `d3.scaleLinear` with clamping. A transition animates the initial hue from 0 to 70 on load, while tick labels show degree values. The visualization renders entirely in SVG, with layered track lines for visual depth.

D3.js Round Slider

This example shows a round slider built with D3.js, where a draggable handle moves along a circular track to represent a value. The visualization renders an SVG circle as the slider’s circumference and a small draggable dot that users can click and pull around the ring. The code uses D3’s `d3.drag` and `d3.event` to handle pointer interactions, calculating the handle’s position via trigonometric functions (`Math.acos`, `Math.sin`, `Math.cos`) based on its distance from the center. The slider’s state is stored in a simple data array, and the handle’s color changes from steelblue to red while dragging, as defined in the accompanying CSS.
