A gauge chart displays a two-segment proportional breakdown, with values that can be adjusted via buttons or a drag-to-resize control. The semi-circular arc uses d3.pie and d3.arc, animating transitions with transition.attrTween and interpolate. A separate bar chart, rendered with SVG and d3.scaleBand, updates its height and color scale on data changes, using a ResizeObserver hook for responsive dimensions. Both components react to state updates, with d3.v5 driving the SVG rendering and React hooks managing lifecycle.

[07] Gauge Chart - Using React Hooks with D3

A gauge chart shows a single dynamic value as a two-part donut arc, with the current proportion displayed as a text label. The chart responds to controls that adjust, filter, or append to the data array. The code uses React hooks (`useRef`, `useEffect`) to manage the D3.js SVG rendering, with D3's `arc` and `pie` functions calculating the arc paths. Animated updates are handled via `transition.attrTween`, interpolating between previous and new arc data. The `d3.drag` API allows the user to horizontally drag a button to resize the container, triggering the gauge to update reactively.

Fork of [07] Gauge Chart - Using React Hooks with D3

This example demonstrates a gauge chart built with React Hooks and D3 v5, where users can resize a video element and a draggable container while buttons adjust, filter, or append data values. The gauge renders as an animated SVG arc using `d3.arc` and `d3.pie`, transitioning between states via `transition.attrTween` with `d3.interpolate`. A separate bar chart uses D3 scales and axes with a `ResizeObserver` custom hook to handle dynamic container dimensions. Data updates trigger React state changes, which re-render both visualizations.

Gauge

This example presents a gauge visualization that displays a single numeric value on a semi-circular arc, using a colored gradient to represent the range from minimum to maximum. The gauge updates dynamically with an animated pointer that transitions smoothly to a new random value every few seconds, simulating real-time data changes. Built with D3.js v2, the visualization uses `d3.svg.arc` for the segmented ring, `d3.layout.pie` for tick generation, and `d3.scale.linear` to map the input domain to angular positions. The pointer’s movement relies on D3’s `transition` with an elastic easing, and the gauge’s color scale is defined by `d3.interpolateHsl`, while labels are positioned via rotation transforms.

A bar chart displays counts for letters A through G, with the tallest bar representing A and values ranging from 3 to 200. Clicking a bar highlights it with a darker color and increased opacity, while dimming other bars, using d3-scales scaleBand and scaleLinear for positioning. The React app integrates with D3 v7, loading data from a CSV file via d3.csv through a ResizeObserver for responsive sizing.

Responsive chart

A responsive bar chart built with React and D3 v5 updates its layout and axes to match the container’s dimensions via a custom `useResizeObserver` hook and the `ResizeObserver` API. Three buttons control the data: incrementing each value, filtering out values above 50, and appending random numbers. Bars render as SVG `rect` elements with smooth transitions, while hover tooltips appear as text. Axes are generated using `axisBottom` and `axisLeft`.

Gauge

This example shows a circular gauge with a colored arc, tick labels, and an animated pointer that moves with an elastic ease. The gauge is driven by random data values, with the pointer rotating via a `transition` on its `transform`. Built with D3 v2, it uses `d3.svg.arc` for the ring, a linear scale for value mapping, and `d3.layout.pie` for tick segments. The pointer rotates through a simple rotational transformation rather than redrawing its path.

[06] Responsive Chart Components with ResizeObserver - Using React Hooks with D3

A bar chart demonstrates responsive sizing with React and D3, using a custom `useDimensions` hook with `ResizeObserver` to track container dimensions. The component re-renders axes and bars whenever the wrapper resizes, computing `scaleBand` and `scaleLinear` scales from the observed width and height. Interactive buttons adjust, filter, or append data, while the chart animates transitions via D3's `transition` method. A draggable button resizes the container, triggering the observer. Styling uses inline SVG with CSS transforms, and tooltips appear on hover with `mouseenter` events.

SVG Face

A circular gauge displays the value 158 out of 158 as 100%, with a needle rotating to the final position and labeled start, end, and current values. The chart is built with React components that define SVG elements, while D3’s `arc` generator and `scaleOrdinal` color scale construct six colored segments around the gauge. The needle, percentage text, and value labels are positioned using SVG transformations computed from the percentage. The implementation uses d3 v6 and React 17.
