📋 Data Format Guide
CSV / TSV: First row must be column headers. Each row is one record.
Example: Date,Product,Revenue,Units,Region
JSON: Provide a top-level array of objects with consistent keys.
Example: [{"date":"2024-01-01","revenue":12500,"region":"North"}]
Best practices: Include a date/time column for trend charts. At least one numeric column is needed for KPIs. Column names with spaces are supported. Keep files under ~100 k rows for optimal browser performance.
