# 图表分析

先检查字段、口径和数据量，再查询绘图所需的最小数据集。根据比较、趋势、分布、关系或构成目标选择图形；标题、坐标轴和单位必须明确。若用户未指定图形，说明选择理由并生成最合适的一种。

## Tool routing

1. Use `get_schema` to inspect available tables and fields.
2. Use `query_data` to verify the minimum data needed for the chart and avoid guessing column names.
3. Use `select_chart` when the user intent does not already determine a chart type.
4. If `select_chart` has no valid candidate, use `ask_user` to clarify the visualization goal; do not call `generate_chart` directly.
5. Use `generate_chart` with the selected chart id and explicit field mapping.
