Flowchart generated with tikz is too big for the slide - How to adjust the size?

Question

I generated a flowchart using tikz. The flowchart is way too big for the slide as seen on the attached picture. .

Answer 1

I agree with the suggestions in the comments that the most straightforward solution would be to decrease the scale.

Another (perhaps clunkier) thing you could do is to split the text "Transformation Process" into two lines, so that the line with that label is shorter. See here: Paragraph in TikZ

Answer 2

• It seems that for writing of your code you use some online generator (in hope, that this is short way to your image)
• Unfortunately, generated code is fill of clutter, so it is not easy to introduce necessary changes, that it can be fint on beamer frame. Consequently I redraw it from scratch ...
• Image is still wider than text area. Therefore I use \small font size (you may further reduce it to `\footnotesize 7 and make nodes narrower).
