## What it is
RxViz is an animated web playground that visualizes Rx Observables: you enter JavaScript whose last expression evaluates to an Observable, and it renders an animated SVG timeline of the values the Observable emits over time. It works as a hosted web app, can be run locally, and is also published on npm as React components for visualizing Observables.

## Use cases
- visualize rxjs observables as animated marble diagrams
- watch how an observable emits values over time
- debug or understand higher-order observables visually
- generate svg observable timelines for presentations
- learn reactive programming by experimenting with rxjs operators
- share runnable observable examples with others

## When to choose
- you want a zero-install, browser-based way to see an Observable's emission timeline animated
- you need copyable SVG marble diagrams of Observables for slides or documentation
- you are teaching or learning RxJS and want intuition for intervals, errors, and higher-order Observables

## When to avoid
- you need actively maintained tooling - the project is explicitly looking for maintainers
- you want production monitoring or observability of live streams inside your application, since this is a playground, not an APM tool
- you need to visualize reactive streams in languages other than JavaScript, since it evaluates JS code and subscribes to Observable-like values
