What program is suitable for drawing the logical structure of the site?

Question

HTML

For the future site of the travel agency, you need to create a visual representation of its structure, in other words, draw a diagram. I understand that it is possible both on paper and in Photoshop, but there are special programs for solving such problems, not just sites, but logical structures in general.

Answer 1

You just need a beautiful scheme, such as the main page leads to sections 1 2 3 4, which lead to such and such subsections.

MS WORD - SmartArt
4 seconds and the scheme is ready.

Answer 2

I use the free draw.io service .
Many people like to draw in mind-mapping services like mindmeister.com/ru .
If you need a desktop client (why?), then XMind .
