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`.

Using React (Hooks) with D3

  • [04] Animated bar chart
  • scaleBand for mapping categorical scale to bands
  • selection.transition() to animate properties
  • Flipping bars with transform scale -1 to animate the upper end
  • Linear scale color interpolation
  • scale.clamp() to limit interpolation at domain ends

[05] Interactivity - Using React Hooks with D3

This interactive bar chart demonstrates how React hooks and D3 v5 work together to create a dynamic, animated visualization. The example uses `useState` and `useEffect` to manage a mutable data array, while D3's `scaleBand`, `scaleLinear`, and `join` method handle the rendering of SVG bars and tooltips. On mouseenter, a tooltip text element appears with data binding, positioned using the band scale’s index value, and animates its opacity and y-position via `transition()`. Buttons trigger data updates—increment, decrement, filter, or append—which re-render the chart through the React state change. The code also demonstrates axis generation with `axisBottom` and `axisRight`, applying a color scale to bar fills based on value.

[03] Axes and scales - Using React Hooks with D3

This example shows a line chart of an array of numeric values rendered as a smooth, cardinal-curved path with labeled axes. The code uses React Hooks with `useState` and `useRef` to manage data and the SVG element, while D3 v5’s `scaleLinear`, `axisBottom`, `axisRight`, and `line` with `curveCardinal` construct the visualization. Buttons update or filter the data, triggering a re-render that redraws the line and axes against a fixed 900×400 SVG viewport.

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.

Animated Chart

A React component renders an SVG bar chart of annual values, with three bars for the years 2020 through 2022. A button click swaps the dataset, triggering a smooth transition where the bars animate their height and vertical position over one second using d3’s `transition`. The chart uses `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.selectAll` to build and update the visualization within a `useEffect` hook on data changes.

Untitled

This example presents an interactive bar chart visualization built with D3 v2 and React, rendering as an SVG with animated transitions. It displays categorical data along the x-axis with corresponding numeric values on the y-axis, using a drop-shadow filter effect on the bars. The chart dynamically rescales its ordinal and linear scales based on the input data, with axis tick labels drawn from a caption mapping. The code leverages jQuery for DOM manipulation, D3’s `d3.scale.ordinal`, `d3.scale.linear`, and `d3.svg.axis` APIs, and applies a custom SVG filter for visual styling.

Basic Bar Chart Animation Test (Fixed Data)

A bar chart in React animates changes to its data values and color scale. Users can adjust the displayed values through buttons that increment, decrement, filter, or add random data points. Built with D3 v5, the visualization uses `scaleBand` and `scaleLinear` for axes, while `transition` animates bar heights and fill colors over 1000 milliseconds. Hovering over a bar reveals its value via a tooltip with a 500-millisecond animation. The chart renders in SVG, with axes positioned using `axisBottom` and `axisRight`.

[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.

s Fork of Untitled

This example shows an interactive, animated bar chart built with React and D3 v2, where each bar is rendered as an SVG rectangle with a drop-shadow filter. The chart uses a hierarchical data structure, displaying captions as x-axis tick labels and mapping numeric values to bar heights via `d3.scale.ordinal` and `d3.scale.linear`. Data transformation and bar layout are handled by custom functions called from a jQuery document-ready handler, with axes generated using `d3.svg.axis`. The visualization updates dynamically, though the specific dataset source is not shown in the provided code.
