As part of the last push, you might notice things looking a bit different on our website!
As the number of available sequences has grown, we've looked for ways to better display them - so they can be useful within the context that matters, while still giving a global view.

We've moved to a new system where we can do both! We're now running 'Global' builds (nextstrain.org/ncov) which try to show a balanced overview by subsampling down to 120 seqs per division, per month, per year.

However, to ensure densely-sampled views are still available, we've introduced 'Regional' builds - for Asia, Africa, Oceania, North America, South America, & Europe.
These highlight seqs from that area (color), while putting the global context less prominently (grey).

Here, seqs from the focal region are sampled at 300 seqs per div/mnth/yr, to give a much higher-resolution view. The 'context' samples from other regions are sampled less-densely at 20 seqs per div/mnth/yr.
This allows clearer views of focal seqs at all geographical levels!

Region builds aren't linked yet on the main Nextstrain landing page (they will be soon!), but can be found in the description (under graphics) of each build - or check them out from the next tweet!

We'll be building on this in the future, to offer even more views of #COVID19 #SARSCoV2 #hCoV19 research as more seqs come in!
A big thanks to the Nextstrain team, in particular @hamesjadfield @richardneher @trvrb @firefoxx66, who made these new Regional views possible! 🙌🏻
