Upload a CSV file containing sieve analysis data to generate gradation envelopes.
- CSV must contain a Sieve OR Diameter (in mm) column. Standard sieves (e.g., "No. 4", "3/4"") will automatically map to their diameters.
- Subsequent columns represent material samples (e.g., 'Sample A').
- Values can be single percentages (e.g.,
100) or ranges (e.g.,70-100).
| Sieve | Diameter (mm) |
