Lucidchart

This is a very impressive app if you take your time and LEARN it. The features are rich, the shapes are flexible, PLENTY of customization at every level, etc. I can't say enough good things about this app. I like to construct my process flow charts (science & engineering) using blank canvas with a grid on various page sizes, and this app allows me to do that. Even the line weights, the arrow type, the text size, etc. are customizable. The AI is OK, but I'm sure it will improve. THANK YOU!
