This example demonstrates the d3-annotation library by rendering four labeled annotations on a blank SVG canvas, each with distinct connector styles, note wrapping, and alignment settings. The annotations include basic labels, arrow and dot connector ends, a curved connector, and a circular callout type, all colored pink. Built with D3 v7 and the d3-annotation plugin, the code uses `d3.annotation()` and `d3.annotationLabel` to position notes via explicit x, y, dx, and dy coordinates without any scales or data binding. The SVG background and Lato font styling are defined inline in the HTML.

D3 Annotation Example

This example demonstrates the d3-annotation library, which adds customizable labels, connectors, and callouts to an SVG visualization. It displays four distinct annotation styles—basic labels, labels with arrow connectors and text wrapping, curved connectors with dot endpoints, and a circular callout—placed on a blank white canvas without any underlying data or scales. The code uses the `d3.annotation()` factory method with `d3.annotationLabel` and `d3.annotationCalloutCircle` types, configuring properties like note position, offset, and connector style. Each annotation is manually positioned with x/y coordinates and rendered by appending a group to the SVG.

Annotation Label Sandbox

This example showcases the d3.annotation library by rendering several annotation types—including `d3.annotationLabel` and `d3.annotationCalloutCircle`—within an SVG on a white background. It demonstrates how to configure note labels, titles, text wrapping, alignment, connector endpoints (arrow and dot), and curve types for connectors, with annotations positioned at explicit x and y coordinates. The code uses D3 v4 to select the SVG element, append a `<g>` group, and call the `d3.annotation()` generator with an array of annotation objects, each specifying a custom color and optional subject settings like circle radius.

Fork of Annotation Label Sandbox

This example demonstrates how to add a single annotation label with an arrow connector to an SVG canvas using the d3-annotation library. The code creates a text title and subtitle, then defines an annotation object with custom note text, title, wrapping width, and alignment, along with a connector ending in an arrow. The annotation is rendered via `d3.annotation()` and `d3.annotationLabel`, with the SVG display styled using CSS, including the Lato font and a white background. The underlying data is hardcoded in JavaScript as an array of annotation objects.

text example

This example demonstrates basic SVG text placement and shape rendering using D3 v4. It positions three text elements with different anchor alignments (start, middle, end) along a horizontal line, showing how the `dx` and `text-anchor` attributes affect text positioning. A polyline traces a jagged path across the canvas, and a circular dot with a lime-green stroke and Indian Red fill uses CSS hover effects to expand its radius and stroke width. The visualization uses D3's selection methods to append elements to an SVG container, with styling applied through inline attributes and CSS classes.

D3

This example showcases a D3 visualization rendered as an SVG within an HTML page, loading the d3.v5 library from a CDN. The code sets up an SVG canvas of 960 by 500 pixels and includes a linked stylesheet, suggesting styled output. The visualization depends on an external JavaScript module (`/js/main.js`) that likely leverages D3’s core APIs to generate the graphics, though the specific chart type or data source is not visible in the provided files.

d3

This example demonstrates a single red circle with a green stroke, centered inside a 500-by-500 SVG canvas. The code uses D3 v6 to select the SVG element, append a circle, and set its radius, position, and fill and stroke colors via attribute methods. The visualization anchors the circle using fixed pixel coordinates, while the body text is styled with a 13-em font size for a bold, minimal layout.

text example

This example demonstrates how SVG text elements can be positioned and anchored in different ways within a D3 v4 visualization. It shows three text strings placed at the same x-coordinate but with distinct text-anchor values (start, middle, end) and dx offsets, illustrating how alignment affects placement relative to the anchor point. The code also includes a simple circle with a CSS class that applies a hover effect, increasing its radius and stroke width. Using D3's selection and append methods, the visualization creates an SVG canvas and populates it with static text and a single interactive dot.

d3 intro

This example demonstrates basic SVG shapes—a blue circle and a magenta rectangle—rendered on an HTML page, with a yellow SVG canvas sized at 900 by 500 pixels. The page also includes commented-out D3 code that would select the SVG, set its dimensions, apply a light blue background, and append a circle at new coordinates. The visible output relies on static SVG elements, while the script shows the intended use of d3.select and d3.append for dynamic manipulation, though it is not executed due to the commented syntax.
