Two draggable points define a line segment, and the visualization highlights both its angle and its normal (perpendicular) line, which rotate and rescale as the points move. The code uses D3 v4.8.0 and a custom `drag` interaction to update an SVG. It draws the angle and normal as colored strokes, while a filled path forms a rectangle spanning the two points, with the distance computed via `Math.atan2` and `Math.sqrt`. The example demonstrates basic geometric calculations and interactive SVG rendering.

Line Drawing

This example demonstrates freehand line drawing through mouse drag interaction. A user presses and holds to create a smooth, flowing path rendered as an SVG stroke on a white canvas. The interaction is built using `d3.drag` to capture pointer events, while `d3.line` with the `d3.curveBasis` curve generates the smooth B-spline path through the collected points. The path elements are appended directly to the SVG container, and the code styles them with a black, three-pixel-wide stroke for a clear visual result.

two line intersection

A draggable line-intersection demo lets the user move four endpoints to see where two line segments cross. The intersection point is drawn as a small circle, which turns red only when the segments actually intersect; otherwise it stays gray. The visualization uses D3’s drag behavior and data joins to bind the points and path elements, while a custom `intersection` function in `geometry.js` computes the crossing and checks whether it lies on both segments. Rendering relies on SVG paths and circle elements, with coordinates updated on each drag event.

line-intersection

This example demonstrates an interactive line-intersection visualization, where users can add points by clicking on a canvas and drag them to see the resulting line segments and their intersections update in real time. The visualization highlights the geometric intersection points between line segments connecting all pairs of points, with a vertical divider separating the interactive area from a static queue preview. The rendering uses SVG with points, lines, and pair paths, and includes a side panel that shows a scaled representation of the point coordinates. The underlying code provides utility functions for point, distance, angle, and intersection calculations, and uses a sorted array with a custom bisector to manage points.

circle-arc-drag

This example demonstrates how a draggable arc can be reconstructed from three movable points, showing the relationship between a circle's geometry and its SVG path. The code uses D3 v3’s `d3.behavior.drag` to update point positions, then calculates the circumcircle and radius via trigonometric formulas, applying the large-arc and sweep flags to render the correct arc. The visualization starts with a pre-defined path parsed into three points using `getTotalLength` and `getPointAtLength`, and the SVG `path` element updates on each drag event. Circles and paths are styled with strokes and fills, with the background set to black.

Free Hand Line D3 v4

This example demonstrates freehand line drawing in an SVG canvas. The visualization begins with a pre-generated curve and prompts the user to drag the mouse anywhere to create additional paths. It uses D3 v4's drag behavior and line generator with a basis curve to smoothly interpolate the points collected during the drag. The rendered path is styled as a tomato-colored dashed stroke, and the code creates the SVG container dynamically on the page.

Untitled

This example demonstrates animated line drawing in SVG using D3.js. Four data points (x, y coordinates) are plotted as circles colored yellow or blue based on their x-value, with a natural cubic spline curve passing through them. The line initially appears with a dash offset and transitions to full visibility over three seconds using D3's `transition()`, `easeLinear`, and a repeating `on("end")` callback. The `d3.line()` function with `curveNatural` generates the path geometry in a React environment.

html-line-chart

A single HTML page renders a magenta line and area chart from 20 random points, using two stacked `<div>` elements with CSS `clip-path: polygon()` to draw the shapes. The code, authored by 1wheel, generates the polygon path strings from the data via `d3.scaleLinear` and `d3.format`, offsetting points slightly to create the stroke effect. A simple static visualization, it highlights the use of pure CSS clipping for SVG-free line rendering, relying only on D3 scales and formatting utilities.

Untitled

This example demonstrates how to connect multiple pairs of points with straight lines in a Cartesian coordinate system using D3.js v3. The visualization renders three separate line segments, each defined by two endpoints, on an SVG canvas with labeled x and y axes. The code uses d3.svg.line() to generate the path data, d3.scale.linear() for coordinate mapping, and d3.svg.axis() to draw the axes. Data is stored as an array of coordinate pairs in JavaScript, and each line is appended as an SVG path element with a distinct stroke color.
