* Build the venn/euler region data from the raw spreadsheet sheet |
| 1607 |
* |
| 1608 |
* Two shapes are supported and detected from the data: |
| 1609 |
* - Region rows: two columns of [set combo, value] where the combo cell joins set names with & |
| 1610 |
* e.g. ['Soccer', 12], ['Tennis', 8], ['Soccer & Tennis', 3] |
| 1611 |
* Values are the exclusive counts for each region exactly as they should display |
| 1612 |
* - Membership lists: one row per set with the set name in the first cell and its member |
| 1613 |
* names in the cells after it (the same row-per-entity shape boxplot uses) |
| 1614 |
* Exclusive region counts are computed from the shared member names |
| 1615 |
* |
| 1616 |
* The output honors the chartjs-chart-venn layout contract: |
| 1617 |
* - All 2^n - 1 regions are present, zero-filled when absent from the data |
| 1618 |
* The library derives the set count as log2(length + 1) so a partial list is a hard error |
| 1619 |
* - Regions are ordered degree-ascending then lexicographic by set index |
| 1620 |
* The library maps region i to layout slot i and ignores the sets arrays for positioning |
| 1621 |
* - labels leads with the n set names in set order followed by the ' ∩ ' joined region names |
| 1622 |
* The library reads set-name labels from labels[0..n-1] |
| 1623 |
* |
| 1624 |
* @param array $sheet raw spreadsheet data (rows of cells) |
| 1625 |
* @param string $parse_in rows or columns |
| 1626 |
* @param bool $for_euler when true sets with a zero total are dropped since they would |
| 1627 |
