## What it is
A VS Code extension that provides a visual watch window for inspecting data structures during debugging. It evaluates debug expressions and renders watched values as rich visualizations like graphs and tables.

## Use cases
- visualize linked lists and trees while debugging
- watch data structures with rich visualizations in VS Code
- inspect complex data structures during a debug session
- visualize JSON expressions while debugging JavaScript or Python
- understand algorithm behavior by watching data change step by step

## When to choose
- you debug data-structure-heavy code in VS Code and want more than the plain watch view
- you work in JavaScript/TypeScript with full data extractor support
- you want to see graphs, trees, or lists rendered live while stepping through code

## When to avoid
- you don't use VS Code or its debug adapters
- your language only has basic support and you can't serialize structures to JSON
- you need a standalone debugger rather than an editor extension

## Facets
- artifact type: plugin
- maturity: active
- function: data-visualization, developer-tools, editor
- domain: developer-tools, data-visualization
- platform: editor-plugin, cross-platform
- tags: vscode-extension, debugging, watch-window, data-structures, visualization
