Chart and #annoplot library now further revised to more fully address sparsity of #CDC data.
Most recent dataset, updated Friday, shows four XFG lineages, reflecting variants broken out by CDC in recent months, together outpacing growth of parent and remaining siblings.
Meanwhile, Nimbus 1.8.1 / PQ family still holding out at near a twelfth of total estimated share.
Note that, in absence of robust data from states, CDC has given up modeling historical estimates, instead giving only shares of reported sequences.
Raj's dashboard, updated three weeks ago, showed Stratus dynasty with diversified XFG.3 family at plurality, accounting for still over a fifth of all samples, with XFG.14 already over a tenth.
GISAID data for the most recent three-plus-week period was dominated by paltry submissions from New York (146 sequences), followed by Minnesota (129), California (39), Illinois (38), Massachusetts (33), and Nebraska (27).

Reskin of CDC's Variants Nowcast, and any significant variants in GISAID not broken out by CDC.
Four bar-style tree-charts, for four-week periods through Dec 21–Jan 17. Legend of last four-week period, organized by subheadings of color-grouped families and convergent clusters. Percentages overlay each color key, reflecting share as of most recent tree-chart.
Essentially all Omicron B.1.1.529 / BA dynasty. Stratus XFG family accounts for over four fifths share.
For 11/23–12/20, packed bubble charts fill single-variant tiles, indicating diversification (per GISAID) not apparent from CDC's Nowcast.
