A JavaScript library for creating smart SVG text boxes with automatic line wrapping and font size scaling.
d3plus-text is a JavaScript library designed to create and manage text boxes within SVG graphics. It automatically handles line wrapping and font size scaling to ensure text fits perfectly within specified dimensions, which is especially useful for dynamic data visualizations where space constraints vary. The library provides a configurable API for precise control over text appearance and layout.
Frontend developers and data visualization engineers who need to programmatically place and format text within SVG-based charts, maps, or custom graphics, particularly those using D3.js or similar frameworks.
It eliminates the tedious manual calculations for text fitting in SVGs by offering automatic, intelligent layout algorithms. Developers choose d3plus-text for its specialized focus on SVG text, robust feature set for complex typography, and seamless integration with the D3 ecosystem.

Automatically breaks text into lines based on container width using the textWrap function, preventing overflow without manual calculations.
Adjusts font size to fit within defined bounds via the fontResize method, ensuring readability in varying container dimensions.
Allows rendering of basic HTML tags like <b> and <i> with SVG styles, configurable through the html method for lightweight rich text.
Includes the fontExists utility to detect available fonts from a list, improving cross-platform compatibility without extra setup.
Only supports a few simple HTML tags; complex rich text or nested structures are not handled, as admitted in the html method documentation.
Tightly integrated with D3 and SVG, making it less suitable for projects outside this stack and adding a learning curve for non-D3 users.
The chainable API with numerous methods like delay and duration can be overkill for basic text rendering, and the documentation lacks beginner-friendly tutorials.
