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.

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 (Circles - Fixed Data)

This example demonstrates how React hooks can manage D3-driven SVG circle updates with fixed data. The app initializes an array of seven values, rendering each as a grey circle with a blue stroke, positioned via attributes calculated from the data. Two buttons trigger state changes: “Update Data” adds five to every value, while “Filter Data” removes values above 35, causing D3’s join method to add, remove, or update circles accordingly. The code uses the `useRef`, `useState`, and `useEffect` hooks, alongside `d3.select` and `.join()`, with React 16.12 and D3 v5.

[02] Curved Line Chart - Using React Hooks with D3

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.

[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.

Line Charts

This example is a minimal line chart demonstration that renders a single static chart using the D3.js library (v5) within a React framework. The visualization is powered by code that utilizes D3’s data-driven document approach to map a dataset to SVG paths, creating a line graph. While the specific data source is not provided in the visible files, the implementation focuses on core D3 APIs for scaling, axis generation, and path construction. The chart is displayed at the center of the page with a large text size, emphasizing the simplicity of the setup.

line chart - d3

This example shows a line chart built with D3.js within a React application, rendering a two-dimensional data series as a path across a Cartesian coordinate system. It uses D3 scales and axis generators to map data values to pixel positions and display tick marks and labels. The chart is drawn using SVG elements created through D3’s selection and data-join methods. A simple dataset is hardcoded in the script, and the visualization updates the line based on the provided points. It relies on the D3 v3 API, including `d3.svg.line`, `d3.scale.linear`, and `d3.svg.axis`.

[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.
