What is the current behavior? (You can also link to an open issue here)

1. ngx-graph is compatible with recent versions of Angular, although the package.json requires updating so users can uptake the library without warnings.
2. There are some inconsistencies with how ngx-graph renders nodes that allow for strange behavior when implementing a clean UX during load, especially when using a loading indicator to wait for when the graph can be displayed.
3. Documentation Portal was built with JIT and incompatible with recent versions of Angular.
4. tslint is deprecated
5. Built on a legacy version of Node.js in CI

What is the new behavior?

1. Updated and tested against Angular 18
2. Fixed issues with the way nodes gain dimension, fixed other bugs to allow for cleaner experience on load
3. Replaced DocSPA with Storybook
4. Migrated tslint to eslint
5. Now built with yarn and Node 20

Does this PR introduce a breaking change? (check one with "x")

• Yes
• No

If this PR contains a breaking change, please describe the impact and migration path for existing applications: ...

The internal changes combined with upgrading Angular from 13 -18 could introduce different behaviors during load, although all previous examples and instances of the ngx-graph used internally work with the changes.
