This interactive visualization helps you understand square roots through a visual grid representation.
The blue squares show perfect squares (1, 4, 9, 16, etc.), growing darker as the numbers get smaller. The red frame shows any square root you select - both perfect and irrational.
To use:
1. Enter a number (0-100) or use the slider
2. Watch the red frame adjust to show the square root
3. Look at where it falls between perfect squares
4. The tooltips show the exact square root value
