I am drawing a diagram with
tikzpicture. The main idea is to draw several boxes of texts framed, and link them with lines...
What I know is using
\filldraw to draw boxes,
\node to write one line of text, and
\draw to make a line. But I have to adjust every coordinator of every element... So my question is:
1) Is it possible to write a text of several lines?
2) Is it possible to frame a text of serveral lines?
Could anyone help? Thank you very much!
