A family of three D3.js path generators for creating aesthetically pleasing curved arrows between points.
swoopyarrows is a JavaScript library that generates curved arrow paths for connecting points in data visualizations and diagrams. It solves the problem of creating visually appealing annotations by providing three distinct arrow styles—swoopy, loopy, and kooky—that replace straight lines with elegant, customizable curves. Built as a lightweight extension for D3.js, it simplifies adding decorative yet functional arrows to SVG graphics.
Data visualization developers and designers using D3.js who need to create annotated charts, diagrams, or interactive graphics with aesthetically pleasing connections. It's particularly useful for those working on editorial graphics, explanatory dashboards, or any project where visual clarity and style are priorities.
Developers choose swoopyarrows for its simplicity, visual elegance, and seamless integration with D3.js. Unlike basic line generators, it offers three distinct arrow styles with fine-tuned control over curvature, coils, and randomness, enabling creative annotations without complex math or custom SVG path coding.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides three distinct generators—swoopyArrow, loopyArrow, and kookyArrow—each with configurable parameters like angle, radius, and deviation for varied visual effects, as detailed in the README examples.
Built to work with D3.js v3 using familiar x and y accessors similar to d3.svg.line, making it easy for D3 developers to adopt without learning new patterns, as shown in the code snippets.
Can accept arrays of points or DOM elements, allowing arrows to be generated between dynamic page elements, demonstrated in the README with offsetLeft and offsetTop accessors.
Minimal setup required; just include the library and use it like d3.svg.line, with clear code examples for each arrow type reducing implementation time.
Requires D3.js version 3, which is outdated compared to current versions, limiting compatibility with modern D3 projects or those using newer features.
Currently only supports arrows between two points, as admitted in the 'To-do' list where handling more points is listed as a future improvement.
Lacks planned enhancements like Adobe Illustrator-style SVG markers and integration as a d3-shape custom curve module, indicating incomplete development.
kookyArrow uses randomness for kinks, which may not be suitable for applications needing reproducible or controlled arrow paths every time, as noted in its configuration.
