This interactive visualization demonstrates the Monte Carlo method for estimating the value of π. A sky-blue circle is drawn on a square canvas, and users can add 100 randomly placed steel-blue points at a time via a button. The display updates counters for points inside the circle and the total, calculating an estimate of π as 4 times the ratio of inside points to total points. Built with React and D3.js, the app uses D3’s selection API to append SVG circles and calculates distances mathematically to determine whether each point falls within the circle.

Fork of Value of PI

This interactive Monte Carlo simulation estimates the value of pi by randomly placing steel-blue points inside a square and counting how many fall within an inscribed sky-blue circle. Each click of the "Add 100 Points" button appends 100 new circles to an SVG canvas using D3.js selection and append methods, while React state tracks the running totals. The estimate updates in real time, calculated as four times the number of points inside the circle divided by the total points, with the current counts and approximation displayed in a grey overlay panel.

Value of PI

This interactive visualization demonstrates the Monte Carlo method for estimating the value of π. By randomly placing points within a square, the application calculates the ratio of points falling inside an inscribed circle to the total number of points, updating the π approximation in a readout panel. The React component uses D3.js for SVG rendering and state management. A button adds 100 points per click, instantly updating the counts and the elliptical estimate. The code leverages the `d3.select` API for SVG creation and `useState` for tracking point coordinates and calculations.

Fork of Fork of Hello HTML

An interactive SVG visualization renders a single circle that follows the mouse cursor, with its radius dynamically scaling based on the cursor's combined x and y coordinates. Built with React and D3.js v7, the application tracks mouse movement through React's event handling and updates the circle’s position and size in real time. The rendering layer uses an SVG viewport of 960 by 500 pixels, and the circle’s radius is calculated as the sum of the cursor’s x and y positions divided by 30.

Fork of Fork trying to get the donut plot IPIPIPI

This visualization displays a proton daily QA report as a donut chart with multiple labeled segments. Each arc represents a measurement parameter such as PositionX, SigmaY, or Intensity. The SVG rendering uses React components with D3’s `pie` and `arc` generators to create the donut layout, while the `FaceContainer` organizes the overall composition. A background area path and tab-like header frame the chart.

Fork of Fork of Fork of Mouse Follower

This visualization shows three colored circles positioned statically within an SVG canvas: a blue circle at the top left, a red circle in the middle, and a green circle on the right. Built with React and D3.js v7, the code uses `d3.select` to append each circle via `svg.append("circle")`, setting coordinates and fill colors through `.attr` and `.style` methods. The rendering approach relies on SVG elements within a React component, with the circles’ placements hardcoded despite the title referencing a mouse-follower interaction.

Fork of Fork of Fork of Rendering Data with React & d3

A radial burst of CSS named colors, rendered as a pie chart where each wedge represents one color from a dataset loaded via `d3.csv`. The React component uses the `useEffect` hook to fetch the data, then `d3.pie` and `d3.arc` compute the wedge geometry, which React renders as SVG `<path>` elements. The fill of each path is set directly from the color’s hex value, creating a full circular spectrum. The visualization demonstrates combining D3’s data-joining utilities with React’s declarative component rendering.

Fork of Fork of Circles with D3

This visualization presents a set of colored circles overlaid on vertical bars, with clickable circles that highlight their selection with a black stroke. Data consists of 14 items with x, y, radius, and fill color properties. The code uses React hooks to manage the selected circle's ID and D3 v7's `select` and `join` methods to bind data and render SVG elements. Clicking a circle triggers `setSelectedId`, causing a re-render that updates the stroke attribute on the selected circle.

Fork of Fork of Fork of React & D3 Starter PIE

This example presents a pie chart visualizing the distribution of students who use AI compared to those who do not, based on a CSV dataset loaded from GitHub. The chart uses d3.pie and d3.arc to generate SVG slices, with d3.rollups aggregating counts from the loaded data. Interactive tooltips display exact student counts and percentages on hover, while percentage labels appear inside each slice and a legend shows category totals. The color scale uses d3.scaleOrdinal with a custom palette.
