+A major problem that we have been struggling for several weeks is almost solved. We have been looking for a combination of a good simulator and a FSM visualizer. We are using Habitat, but we didn't find any suitable FSM visualization tool.
 
-Robin just found a python library that can do great job on FSM visualization - [Python State Machine](https://python-statemachine.readthedocs.io/en/latest/index.html). It can generate clear FSM, just like SMACH. Here is an example of a number guessing machine.

-Robin also implemented this library into Habitat, and it works well as a time based moving robot. There still have two problems to solve: the keyboard doesn't work and `pygame` frame-rate gets extremely low after implementing FSM visualizer.
+Robin also implemented this library into Habitat, and it works well as a time based moving robot. There still have two issues with the code: the keyboard doesn't work and `pygame` frame-rate gets extremely low after implementing FSM visualizer.
 
-I tried to solve them, and the keyboard one has solved. The low frame-rate was caused by every time it generates a graph as a `png` image file, and for every frame the visualizer is updating the graph. I partially solved this by asking it just generate a graph only when the state changes. The result gets slightly better, the frame-rate is high when the robot keeps in the current state. When it changes between states, the frame-rate is slow as before but the experience is much better. If the graph is something like a canvas with draggable nodes not images, I think this problem would be solved.

If the graph is something like a canvas with draggable nodes not rendering as some static images, I think this problem would be solved.

-- When I wanted embed some `p5.js` sketches, the `p5.js` doesn't load automatically, I had to refresh pages. I found this might be an issue with SPA(single-page application). SPA is a type of website that works inside a web browser and behaves more like a desktop application. Instead of loading a new web page every time you click on something, an SPA loads all the necessary code, like HTML, CSS, and JavaScript, when you first visit the website. In the initial page, I don't load `p5.js`, that's the reason when I disable SPA, `p5.js` works correctly. If you want to disable it, go to `quartz.config.ts` to change it.
