Draw an event planning and execution flowchart with Mermaid flowchart TD syntax. Define goals and audience, write the event plan, build the budget; if the budget is not approved, return to the plan. Once approved, confirm venue and date, then run two parallel tracks, arranging materials and speakers and promoting with registration open, which meet at rehearsal. If problems are found, adjust and rehearse again; if not, run the event, handle issues on site, wrap up and settle invoices, then report results and review. Use diamonds for decisions and no parentheses in node text. Output only the mermaid code block.
