LWDA Notice Density Field

Eight nearest-anchor groups organize California-labeled employer records from the DIR notice workbook. Animated marks carry source weights; they are not individual notices or addresses. Color distinguishes three filing periods.

The centers and drifting field retain the original illustrative composition. ZIP reference points determine group membership, not precise positions on this drawing.

What a mark represents

The drawing budget is divided among the 24 group-and-period cells in proportion to their source rows. Whole marks use largest remainders; a mark keeps the same group and period when it respawns. The seed changes placement only. Moving trails are not additional records.

Weights are exact within each group-and-period cell. “Rows/mark” is rounded here; the CSV includes the underlying counts and unrounded quotient. A cell with no mark remains in the source counts.
