You are also shifting the center here

Each shape is different center of the box may not be inside the actual shape. For those hollow shapes there are no exact centers. You just need to find any suitable point that falls inside the shape.

Considering center of the box as origin we can try to find points that intersect with x and y axis. And pick a point in between two intersections:
Demo on codesandbox. It'll take some time to load.

Another solution is to use margin to adjust the position since css is a layout language.

This will prevent element from getting out the coordinates.

Then you could use height:max-content to make the parent div include all child element

It is easiest to work with ggplot when your data is in a "long format", i.e. each row has one X value and one Y value. The tidyr package has the handy pivot_longer() function to do just that.

Also in need to change your plot symbol from "hollow"/"dark" to "open"/"filled"

All the scale_*_identity() are used to use the values stored in the data frame and not the default values.

The cause of the linker errors was this statement:

• It can be done in pure-HTML+CSS (without any SVG).

  • And it can be done in pure SVG too.
    • The SVG-only option will be simpler because SVG has more powerful blending and masking capabilities that aren't (yet) able to be used by HTML elements (CSS boxes).

• I decided to do it for HTML+CSS because I felt like a challenge.

  • This HTML version is animated and the text is fully selectable.
  • This HTML+CSS version can be simplified further by using mask-image: element(#target) which means we don't need the mask-only text, unfortunately Chrome doesn't seem to support element() yet (but Firefox does, though).

• A minor wart is the text-stroke outline does not exactly line-up with the solid white text (at least in Chrome on Windows 10 with my computer's version of Helvetica at 96dpi, but at 192dpi (2x, aka Retina)) in the same browser and computer it looks perfect.

• Here's how it looks at different points in the animation on my machine at 96dpi:
  

• The example implementation below works in the following browsers (at the time of writing):

  • Chrome 98
  • Edge 98
  • Firefox 97
  • macOS Safari Technology Preview (Release 137)
    • It kinda works in macOS Safari 15.2, but you have to click on it first for some reason.
    • It doesn't work in iOS Safari 15.1 (only the outlined text is visible, the solid text doesn't render at all).
    • Because it does work in the Safari Preview browser it should work in the next update to iOS Safari and macOS Safari, however.

This is standard SwiftUI behaviour in iOS 15, as it implements by default the recommendations from Apple’s Human Interface Guidelines, which says tab bars should use filled variants of SF Symbols, while sidebars on iPad should use the outline variant.

The effect is achieved by iOS automatically applying the .symbolVariants environment value, as noted in the symbol variants documentation:

SwiftUI sets a variant for you in some environments. For example, SwiftUI automatically applies the fill symbol variant for items that appear in the content closure of the swipeActions(edge:allowsFullSwipe:content:) method, or as the tab bar items of a TabView.

If you absolutely want to get ride of the fill mode, it’s deliberately made tricky but not impossible. You have to override the supplied \.symbolVariants environment variable directly on the Label element, inside your tabItem declaration:

Im UML, this class means that Every Unit is aggregated into some other Unit.

The UML standard doesn’t cover code generation, so interpretation of this as code depends on which tool you choose. Every proprietary code-generation tool should either stop with an error or provide an additional constructor that creates a new Unit that references itself. Otherwise, what Unit does the caller pass to the constructor for the very first Unit?

Other ways to fix the problem include taking an open-world interpretation of this UML model (where not all true information is present, as is the case for OWL), or loosening the multiplicity to 0..1.

I see at least these issues in your code:

• The wall is built at a random position without taking into account the odd/even division of your cells in potential-wall / not-wall cells (which is the reason why you had this.COLS = this.width*2+1 in the constructor). As a consequence your walls can end up adjacent to eachother, leaving no room for open cells. You should only place horizontal walls at even Y-coordinates, and vertical walls at even X-coordinates.

• The door in the wall is always made at the extreme end of the wall, while the algorithm should make the gap in that wall randomly.

• There is only one recursive call, which means the algorithm is not aware of the fact that a wall generally divides the room into two partitions, each of which should (generally) be further divided up through recursion. So you need two recursive calls instead of one.

If you correct those points it could work. However, I prefer a data structure where really each inner array element represents a cell, and the walls are inferred by properties of those cells. So, no cells will function as wall. Each cell then can track which are its neighbors (4 at the most). A wall can then be implemented by removing a neighbor from a cell (and doing the same in the reverse direction). The visualisation of a wall can then be done with border CSS styling.

Here is an implementation:
