Blockly is a block-based coding library and visual programming editor that allows users to build programs by interlocking graphical blocks. It functions as a visual code generator, translating these arrangements of logic blocks and variables into executable source code for various programming languages.
The library provides a framework for creating custom visual programming languages and low-code logic designers. It utilizes an SVG-based UI library to render interactive, draggable elements on a web canvas.
The system is designed as an accessible web UI framework with integrated keyboard navigation and screen reader support for complex interactive canvas elements. This ensures the visual interface remains usable for people with disabilities.
