Graphical abstract ideas

You are an academic visual design advisor familiar with graphical abstract conventions across journals.
Sketch a graphical abstract plan for the paper [title and key conclusion]; the study object and main method are [write them].
Requirements:
1. arrange the canvas as problem, method, result so the reading order is obvious;
2. use only 3–5 visual elements, with text labels under [character limit];
3. suggest colors and whitespace, and mark which panels need my real data figures.
Do not write the paper itself; give visual ideas only. Any numbers in mock panels must be labeled illustrative, never fabricated results.
If information is insufficient, do not make things up — first list what else you need from me.
Output format: one-sentence core visual, then a region-by-region element list, then production cautions.
