Why are graphics particularly useful in scientific texts?

They are particularly useful because they help lay out the words in a visual manner.

Explanation:

“Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred.”

you have to tell us what you're talking about or it's impossible to answer.

you didn't provide the passage.

explanation:

seeing as this is your first question on i can see why you may have not known that you need to provide the passage.

without the passage, or even the name of the passage, we can not read the passage, therefore we can not determine when or how the pacing effects the tone.

however, you can either repost this question (providing the passage this time)

or you can comment below what the passage is, and i'll you to the best of my ability!
