This example demonstrates a curved line chart rendered as an SVG, where a dataset of numeric values is mapped to a path using D3’s `line` generator with the `curveCardinal` interpolation. The chart initializes with twenty points, and two buttons trigger updates: one increases every value by 5, while the other filters out values below 35, causing the line to redraw dynamically. React hooks (`useRef`, `useEffect`, `useState`) manage the SVG element and data state, while D3’s `select` and `path` joins handle the visual update. The viewport is set to 940 by 450 pixels, with a yellow fill and blue stroke.

[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 React Hook Test (Line - Fixed Data)

This example demonstrates a line chart built with React hooks and D3.js, where a fixed dataset of twelve values is rendered as a smoothed cardinal curve. The visualization updates dynamically through two interactive buttons: "Update Data" increments each point by a constant value, while "Filter Data" removes all points exceeding a threshold. The code initializes the SVG using a React `useRef` hook, then applies D3's `scaleLinear`, `axisBottom`, `axisRight`, and `line` with `curveCardinal` to draw axes and the path. State management relies on `useState`, with effects triggered by the `useEffect` hook responding to data changes.

Basic React Hook Test (Line - Fixed Data)

This example demonstrates a line chart built with React and D3 v5, using fixed sample data stored in component state. The visualization updates interactively when buttons increment every data point or filter out values exceeding a threshold. The code uses D3's `scaleLinear`, `line`, `curveCardinal`, `axisBottom`, and `axisRight` functions to render the SVG. A React `useEffect` hook redraws the chart whenever the state changes, while the `useRef` hook provides direct access to the SVG element for D3 selections.

[01] The Basics - Using React Hooks with D3

This example demonstrates how to combine React Hooks with D3 to render and update a simple SVG scatterplot. A `useState` hook manages an array of numeric data, while a `useRef` hook and `useEffect` hook initialize an SVG canvas using `d3.select` from D3 v5. Circles are appended via `selectAll(...).data(...).join('circle')`, with radius and position derived from each value. Clicking the “Update” button increments the data by 5, and “Filter” removes values over 35, triggering a re-render through React’s state changes.

[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`.

Brush with react(axis)

This example shows a line chart of a small dataset, rendered with React and D3, where the curve updates in response to button clicks that either raise each point’s value or filter the data to those under 50. The visualization uses d3.scaleLinear for both axes, d3.axisBottom and d3.axisLeft for tick marks, and d3.line with curveCardinal to draw a smooth path. The chart is an SVG whose axes and line are re-rendered via a useEffect hook whenever the state changes, with the buttons driving the dataset transformations.

[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.

[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.
