Falling DNA sequencing prices and a growing appreciation of cellular complexity soon unleashed a torrent of genetic data. The tools for gathering data, though, had outpaced those for portraying it. “I was frustrated, reading a lot of the scientific papers and not understanding what they were saying. I just wanted them to be simpler,” said Krzywinski. “There’s nothing I can do to make biology simpler, but I started telling people to make clearer figures.”
To do this, Krzywinski developed Circos, an open source visualization tool that arranges tabular data in circular form. It was a simple idea, but transformative:
