# Project 4: Visualizing Runtime State and Dynamic Behavior

![](screenshot.png)

## Goals:
- Design and implement tools to make active expressions explorable and tangible
  - List active expressions in the system, with meta information
  - Visualize dependencies in an object-centric view
  - Allow to track dependencies between active expressions and over time
  - Visualize reactive behavior over time
