I need to analyze the temporal trend in this Olympic table tennis medals dataset. The card shows `year` as the temporal axis (1988-2024). Let me first check what gold tables exist, as they might have pre-aggregated time series data. ```json { "action": "tool_call", "reasoning": "Check if there are pre-computed gold tables with temporal aggregations before querying raw data", "tool": "get_gold_tables", "args": {} } ```
