"""Diagrama forward P/E x venit pentru 11_selectia_simbolului.md (marcaj pe_venit).

Matrice 2x2: coloane = forward P/E (mic / mare), randuri = venit (creste / scade).
Fiecare cifra si eticheta vine din textul din jurul marcajului sau din citatele
lui (vezi caption-ul din josul SVG-ului). Nu e grafic de pret, deci nu foloseste
svg_candles / pchart.
