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.

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.

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.

colored bar chart

A colored bar chart displays a dataset of numeric values as vertical bars, with color mapping from green through orange to red via a `d3.scaleLinear` domain of 0 to 110. React state management allows the user to increment, filter (values ≤ 50), or randomly append data through buttons, triggering `useEffect` updates. The SVG is rendered using `scaleBand` for x-positioning, `scaleLinear` for y-scaling, and D3 v5 axes. Bars animate on transitions, and mouseenter events create tooltips with D3 text elements that fade in.

Basic Bar Chart Animation Test (Fixed Data)

This example demonstrates an interactive bar chart where users can dynamically alter the dataset through buttons that increase, decrease, filter, or append random values. The bars animate their height and color transitions over one second, with hover tooltips displaying each bar's value. Built with React and D3 v5, the visualization uses `scaleBand` and `scaleLinear` for axes, a `linearGradient`-like color scale mapping values to a red-to-green range, and D3's `.transition()` method to smooth updates to the SVG elements.

[04] Animated bar chart - Using React Hooks with D3

This example shows an interactive animated bar chart where users can increment, decrement, filter, or append values to a dataset, with bars flipping vertically and transitioning smoothly to new heights. Built with React Hooks and D3 v5, it uses `scaleBand` for the categorical x-axis, `scaleLinear` for y and color interpolation, and `selection.transition()` to animate bar heights and fill colors based on a clamped color scale. The SVG rendering uses `transform: scale(1, -1)` to flip bars, with axes positioned via `axisBottom` and `axisRight`.

Range Slider D3 V4

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.

time slider

This example showcases various interactive slider configurations built with D3 v5 and the d3-simple-slider library. It demonstrates core functionalities like simple continuous sliders, step-based sliders for discrete values, and time-based sliders using the `d3.timeFormat` and `d3.timeScale` for date handling. Additional features include filled sliders, range selection, vertical orientation, customized handles, and smooth transitions. The visualization also presents practical applications, such as a New York Times-style slider and a color picker, all rendered as SVG elements with Bootstrap styling for layout.

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.
