Suggestion to improve README with demo section for better understanding of the project.

Hi 👋

I was going through the README and really liked the project.

I noticed that:

• Since DOTRA is a visual tool, a small Demo / Preview section could help new users quickly understand the output.
• The project already uses react-scripts (as seen in package.json)

Would you be open to:

• Adding a Demo section (live link or screenshot/GIF)
• Adding a react-scripts badge alongside the existing tech badges?

If this sounds good, I’d be happy to open a PR for it.
