  As the year 2020 draws to an end, several new strains have been reported for
the SARS-CoV-2 coronavirus, the agent responsible for the COVID-19 pandemic
that has afflicted us all this past year. However, it is difficult to
comprehend the scale, in sequence space, geographical location and time, at
which SARS-CoV-2 mutates and evolves in its human hosts. To get an appreciation
for the rapid evolution of the coronavirus, we built interactive scalable
vector graphics maps that show daily nucleotide variations in genomes from the
six most populated continents compared to that of the initial, ground-zero
SARS-CoV-2 isolate sequenced at the beginning of the year. Availability:
Mutation time maps are available from https://bcgsc.github.io/SARS2/
