Visualization Recommendation

I need to visualize {{data_description}} for an audience of {{audience}}. The key insight I want to communicate is: "{{key_insight}}"

Data shape: {{num_rows}} rows, {{num_columns}} columns
Key variables: {{variables_list}}
Tool: {{visualization_tool}}

Recommend the top 3 chart types for this data and insight. For each recommendation:
1. Chart type and why it works for this specific data + insight combination
2. Which variables to map to which visual encodings (x-axis, y-axis, color, size)
3. Specific design choices (color palette for {{audience}}, annotations to highlight {{key_insight}})
4. Code snippet to create it in {{visualization_tool}}
5. One common mistake to avoid with this chart type

Rank them by how clearly they communicate {{key_insight}} to a non-technical audience.
