## Project Status
Looking for maintainers!
Unfortunately, I don't have the time to maintain this project anymore. If you are interested to help, please reach out to me on Twitter [@moroshko](https://twitter.com/moroshko).
## Description
RxViz simply visualizes a given Observable. Your JavaScript code will be evaluated, and, if the last expression is an Observable, a nice animated visualization will appear.
You can also:
- Control the speed of the animation by modifying the **Time window** input.
- Copy the resulting SVG to include in your next Rx presentation.
- Share the visualization with your friends.
## Examples
### Basic interval
[](https://rx-viz.vercel.app/examples/basic-interval)
### Random error
[](https://rx-viz.vercel.app/examples/random-error)
### Higher order Observable
[](https://rx-viz.vercel.app/examples/higher-order-observable)
### Pause and resume
[](https://rx-viz.vercel.app/examples/pause-and-resume)
## How does it work?
RxViz treats the evaluated Observable as a black box. We rely only on the fact that Observable emits values over time. **RxViz doesn't rely on the internals of RxJS.** This will allow us to visualize [TC39 Observables](https://github.com/tc39/proposal-observable) in the future.
Technically, we subscribe to the given Observable, and, once a value is observed, we simply add it to the visualization. It's that simple!
### How about higher order Observables?
No different. Since a higher order Observable is simply an Observable whose values are Observables themselves, we just repeat the process recursively.
When an Observable value is seen, we subscribe to it. At this point, we create a new "branch" in the visualization.
