New version renders charts too small

[CH-RhyMoore]

Description

The new version of the visualizer is lovely, but (at least on my machine) there is fairly major user experience issue.

The chart is rendered very, very small and there appears to be no way to view it at a larger size other than to zoom in in place. But then the diagram gets cut off vertically and horizontally and requires one to scroll around in a very small space.

The dividing line between the left panel with the chart and the right panel with the chart almost seems like it is supposed to be draggable. When I hover over it I get the drag cursor and it becomes thick and blue. But no matter how I interact with it, nothing allows me to make it smaller (if I click, nothing, if I click and drag, nothing, if I double click, nothing). I can only hover and drag it larger, which I definitely don't need.

Ultimately, it appears to be impossible to view the entire machine's chart at a readable size.

Expected Result

• I expect to be able to view the machine full screen at a zoom level of my choice.
  • (I would also love to be able to export one at a size of my choice like the MermaidJS app, but that's a separate subject, I know)
• I expect to be able to resize the right hand panel to a smaller size or hide it entirely.

Actual Result

• I am only able to view a small amount of the machine in a left hand panel.
• I am only able to make the right hand panel larger.

Reproduction

Additional context

macOS Catalina 10.15.7
Google Chrome 103.0.5060.114
MacBook Pro (so a very common screen size for our industry)

• My vision isn't super great, so the size of the chart matters to me a great deal.
• One of the advantages to the charts is how they enhance documentation. This gets in the way of screenshots. (I spent about 2 hours trying to figure out how to hide certain elements and alter the layout so that I could see things and get screenshots, but what I managed still didn't work for more complex and larger machines).
