This demo shows an interactive SDCurve.js curve editor where users can manipulate a spline defined by four control points. The SVG rendering displays a white curve over a dark background, with the curve dynamically subdivided and smoothed using the dyn-levin algorithm. The code loads biographical data from a TSV file containing 19th-century women writers, though the data-loading routine appears incomplete. Built with React and D3 v3, the visualization supports mouse interaction, including dragging control points and adjusting curve resolution and degree parameters.

working Demo

This demo shows a red interactive curve overlaid on a scatterplot of historical female writers’ birth and death dates from a TSV dataset. Users can drag points on the curve’s control polygon to reshape the smooth spline in real time, with the underlying data points repositioned along the curve. The visualization is built with React and D3 v3, rendering SVG paths via `d3.svg.line` and a custom `SDCurve` class that implements Dyn-Levin subdivision.

curve again.js Demo

This example shows an interactive SVG visualization of a smooth curve generated from a set of control points, with a dataset of historical figures plotted as points along the curve based on their birth dates. The visualization uses the D3.js v3 library with a custom SDCurve object implementing dynamic Levin-type subdivision for curve refinement. Users can drag control points to reshape the curve in real time, and the data points reposition accordingly, illustrating how the curve acts as a timeline mapping individuals’ birth dates to positions in two-dimensional space. The rendering is done via SVG circles and paths, with data loaded from a TSV file.

kidingme.js Demo

This demo uses a B-spline curve generated with the SDCurve library to map the birth dates of notable historical women from a TSV dataset. Each person is represented as a small orange circle positioned along the curve, with the data sorted chronologically by birth date. The visualization supports interactive dragging of the curve’s control points in SVG, allowing users to reshape the curve and see how the circle placement updates in real time. The demo is built with React, D3 v3 for SVG manipulation and event handling, and includes dynamic curve subdivision for smooth rendering.

curve again repair

This example plots the birth dates of historical women writers along a smooth, interactive Bézier curve. The curve is created using a custom SDCurve library, which subdivides a control polygon using a dynamic Levenberg algorithm, and is rendered as an SVG with D3.js. Each birth date is mapped to a point on the curve, with orange circles marking the positions, while the underlying data is loaded from a tab-separated values file (data.tsv) containing names and dates.

continues1.js

This example visualizes a dataset of authors with their birth and death dates by mapping each person to a position along a continuous, interactive Bézier-like curve. The rendering shows orange circles placed along a red skeleton curve, demonstrating a custom curve-subdivision algorithm. The code implements the visualization using D3 v3 for SVG rendering and data loading from a TSV file, while a custom `SDCurve` class defines the curve geometry with adjustable resolution and degree. Users can interact with the curve through mouse events, including dragging and double-clicking.

D3 Curve Explorer

This interactive example shows how different D3 curve types interpolate the same set of draggable points, with buttons to toggle curve families and variants like `curveLinear`, `curveBasis`, `curveBundle`, and `curveCardinal` at various parameters. A sidebar displays a description of the active curve. Users can drag points, add new points via the plus icon, and remove them with the minus icon, all rendered as SVG elements. The code uses D3 v4’s shape API to generate the path data and event handlers for mouse interaction.

Spline Editor

This interactive spline editor lets users add, drag, and delete control points to shape a curve. The visualization redraws the line dynamically using `d3.svg.line` with a selectable interpolation mode from a dropdown menu. Data points are generated programmatically with random coordinates, and rendering uses SVG with elastic transitions for point appearance. The editor relies on D3’s event handling for mouse and keyboard interactions (including DELETE key removal), with point selection highlighted in orange. Animated updates occur through D3 transitions, while the chart area is a large transparent rectangle capturing mouse events.

d3 curve

This example shows a green curve rendered through an SVG path, connecting four user-defined points using D3’s line generator with the natural cubic spline interpolation. The curve’s shape is computed from the point coordinates, which are explicitly set inside the JavaScript code. D3.v5 is used to build the path data, while the path is appended to an `<svg>` element with the ID `svg1`. The page also includes a separate canvas element, though it is not involved in this rendering. The code references `getPointAtLength` to inspect the path geometry.
