SVG Fundamentals

This example demonstrates the basics of SVG rendering using D3.js v7 within a React-compatible setup. The page displays a simple "Hello World" text alongside D3-generated symbol shapes, created via `symbol` and `symbols` APIs. It imports utilities like `ascending`, `range`, and `select` from D3 to handle array operations and DOM selection. The visualization also references a separate module (`something.js`) that computes a string, showing how external JavaScript files integrate with the main rendering logic. The code highlights fundamental SVG manipulation and D3’s modular imports.

SVG Fundamentals SIN CIRCLE

This example shows a field of circles that continuously shift position and size based on a sine wave, animating at 60 frames per second. The code generates data points using JavaScript’s `Math.sin` to compute both the circle radius and its x-coordinate offset, creating a rhythmic, flowing motion. It uses D3 v6’s `select`, `data`, and `join` methods to bind the updated data to SVG `<circle>` elements, updating their `r`, `cx`, and `cy` attributes each frame. The rendering is pure SVG within a full-viewport canvas, with no external data source.

Fork of Fork

An intricate geometric grid emerges as overlapping vertical and horizontal stripes alternate visibility through two SVG masks. Rendered with D3 v6 in React, the visualization layers 100 thin rectangles in each direction, with each mask containing all five D3 symbol shapes repeated across the canvas. The first mask reveals stripes through filled symbols, while the inverted second mask hides them, creating a woven optical effect where symbol outlines define the pattern. The result is a dynamic, mask-driven interplay of shapes and lines.

Fork of SVG Fundamentals

This example demonstrates masking in SVG by creating a grid of horizontal and vertical rectangles, each with a mask applied. Two masks are rendered using D3's `symbol` API, placing geometric shapes like circles and crosses across the canvas. One mask is inverted by using black as the background and white for the shapes, while the other uses the opposite color scheme, causing the grid lines to appear only within the symbol outlines. The visualization shows how D3 selections, joins, and the `attr` method dynamically set mask references and symbol paths.

Fork of SVG Fundamentals

This example demonstrates SVG masking by layering a grid of horizontal and vertical rectangles over a circular cutout. The rectangles are created dynamically using the DOM API `document.createElementNS` with the SVG namespace. Two complementary masks, `circle-mask` and `circle-mask-2`, alternate between white and black fills to control visibility, producing a striped pattern inside the circle while keeping the surrounding area solid. The code relies on raw SVG manipulation rather than a visualization library, with only the `d3-selection` API imported but not actively used.
