Figure 2 from: Mounce R, Murray-Rust P, Wills M (2017) A machine-compiled microbial supertree from figure-mining thousands of papers. Research Ideas and Outcomes 3: e13589. https://doi.org/10.3897/rio.3.e13589

Figure 2 - A typical source input tree raster image (figure 1 from Park et al. 2008). Note the low resolution image quality. As this computer-generated ilustration follows predefined rules and conventions for the visual display of phylogenetic trees, we do not believe that it qualifies as a copyrightable work in itself (see Egloff et al. 2017 for more).
