Bacterial diversity (ten-taxon tree)

Scenario

A microbiologist or bioinformatician pastes a Newick tree string exported from RAxML, IQ-TREE, or MEGA and immediately gets a publication-ready SVG with clade highlights and a branch-length scale bar — no manual layout required.

Annotation key

• newick: "..." — standard Newick format tree string; branch lengths follow : after each taxon name
• [&&NHX:B=98] — NHX annotation; B= is the bootstrap support value (0–100), rendered on internal nodes
• clade id = (taxon, ...) — defines a named clade by listing its leaf members
• [color: "#hex", label: "..."] — colors the clade's subtree and adds a labeled arc
• scale "..." — draws a calibrated scale bar with the given unit label

How to read

The tree shows three major bacterial clades. Blue (γ-Proteobacteria): E. coli, Salmonella, and Vibrio cluster with 98% bootstrap support. Red (Firmicutes): Bacillus, Staph, Listeria, Streptococcus, and Lactobacillus. Green (Actinobacteria): the two Mycobacterium species form a highly supported clade (bootstrap 100). Branch lengths represent substitutions per site — longer branches indicate faster evolutionary rates.
