Real coordinates from the published Carbon-A GFF3. These are model predictions, not experimentally confirmed genes. The blue/green tree colours describe annotation records for an assembly; they do not classify individual loci as known or new.

What is being drawn

Each of the 33,588 strands is a distinct accession from the explorer’s covered-assembly table, mapped through the NCBI taxonomy. No assemblies or taxonomic branches have been invented to fill out the release total.

Equal-width assembly strands preserve count through shared ancestors. At overview scale many strands fall within a pixel; zoom reveals them separately. Radius and branch length are layout choices, not dates or evolutionary distances.

The outer bars sum measured gene_count values from published per-assembly metadata. Bins contain consecutive assembly tips in taxonomy order. Grey base marks indicate the fraction of assemblies without counts; these are not treated as measured zeros. The radial scale is linear and recalculated for each bin size. Colours within the tree classify assemblies; the green outer bars count all predicted loci, regardless of prior annotation status.
