This example demonstrates how D3 v3 renders SVG marker shapes used as line endpoints. It defines four distinct path geometries—circle, square, arrow, and stub—and attaches each as both a marker-start and marker-end to a corresponding element in a group. The code uses `d3.scale.category10` for colors, builds markers via SVG `<defs>`, and positions everything within a fixed margin layout. The visible result is a set of colored, marker-capped paths across the canvas, though the intended connecting lines are commented out.

This example demonstrates basic SVG shape construction on a static HTML page, combining a diagonal line, a rounded rectangle, and a vibrant green circle within a translated group. The visualization labels the shapes as "Rectangle" and "Circle" using monospaced text, while a larger title announces "d3.js 学习 Day01" (D3.js Learning Day 01). The code relies on raw SVG elements—`line`, `rect`, `circle`, `g`, and `text`—styled with inline CSS and attributes like `transform`, `fill`, and `stroke`. No JavaScript libraries are imported; it is a pure HTML/CSS/SVG composition.

This example demonstrates how to begin using D3 version 6, focusing on basic SVG setup and marker definition. The code creates an SVG canvas and defines an arrow marker with a red path, using the `marker` element for reusable arrowheads. It selects the SVG element with `d3.select`. The example includes a YouTube tutorial link in the README, though the visible JavaScript only imports `select` from D3 and selects the existing SVG, showing minimal initialization steps without further interaction or data rendering.

A black cubic Bézier path is drawn on an SVG canvas using D3 v4, with its total length queried via `getTotalLength()`. The example marks two points sampled along the path at 50% and 78% of its length, using `getPointAtLength()` to position small red and blue circles. A green line is then constructed between the two points and extended backwards to the canvas edge, demonstrating how to compute a secant line from arbitrary positions along a vector path. The visualization uses inline SVG elements created through D3's selection API, with styling applied via a linked CSS file.

This example draws a single circle in an SVG using D3.js v5. The circle is appended to the root `<svg>` element and positioned with hard-coded values for its center and radius, using the `select` and `append` APIs. The circle’s radius is set to half the SVG’s height, and its x- and y-coordinates are both set to half the SVG’s height, resulting in a face-like shape centered vertically. The page loads D3 from an unpkg CDN and includes minimal CSS that hides overflow.

This example demonstrates basic SVG rendering with D3 version 7, showing two static circles positioned on a 960×500 canvas. The code directly embeds SVG circle elements in the HTML, using attributes like `cx`, `cy`, and `r` to control placement and size, with the second circle given a red fill. While it includes an empty D3 import and a commented-out text selection, the visualization primarily relies on native SVG markup rather than D3’s data-joining or selection APIs. The page loads d3.min.js from the unpkg CDN, though no dynamic data or interactive behavior is currently active.

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.

This example shows a collection of geometric shapes rendered directly in SVG, including circles of varying radii and colors, a navy line from the origin, and a red path with arc and quadratic curve segments. The code uses plain SVG element syntax within an HTML file, with a commented-out rectangle demonstrating how to toggle shapes. Each shape is positioned explicitly via cx, cy, x, y, and path data attributes, and styling is applied through fill, stroke, and stroke-width properties. The visualization is static, with no interaction or data binding, serving as a bare-bones demonstration of basic SVG drawing primitives in a standalone page.

This example renders a simple static SVG scene containing a path, an inactive polygon with dashed gray styling, and a group of active and tentative shapes including a red circle and dark gray rectangle. The code relies on D3.js version 5.15.0 for element selection and class manipulation via `d3.select` and `.classed`. The SVG is drawn directly in the HTML with inline styling, showing how CSS classes like `.active` and `.tentative` control stroke appearance and opacity.
