"红利分配图" can be translated as "Dividend Distribution Chart" or "Bonus Allocation Diagram", depending on the specific context and the preferred terminology.
"Dividend Distribution Chart" is more commonly used in financial contexts to refer to a visual representation showing how dividends are distributed among shareholders.
"Bonus Allocation Diagram" might be used in contexts where the term "bonus" is more prevalent, such as in employee compensation plans, though it's less standard for referring to shareholder dividends.
For most financial and corporate contexts, "Dividend Distribution Chart" would be the more appropriate and widely understood translation.
