I try to avoid using idioms and proverbs in writing. But sometimes an idiom is so true it is worth explaining.
One picture is worth a thousand words: means a single picture can convey so much meaning it replaces the need for ( is worth ) a thousand words.
Sometimes a single image or diagram will give the right reader so much information.
I hope this picture is conveys a lot of meaning to you.
This image is a remix of other internet memes, feel free to remix as I have done.
