The flowchart flow will be from top to bottom or from right to left. The flow line should indicate which sign will be followed by which sign. No problem if the mark is too big , but the specific shape must be right. Must have flowchart name , author's name and date. It is best to minimize line crossings as much as possible. If the conjunction line is too long, it is better to use the conjunction symbol instead of the line. Comments can also be given with symbols as required.
