Thanks to the concerted efforts of many different contributing studies and institutions, the Malaria Vector Genome Observatory now contains analysis-ready data from whole-genome sequencing of 22,015 Anopheles mosquitoes. Within the last 12 months, more than 10,000 new genomes were added, doubling the total size of the data resource. The first data were also added for mosquitoes from the Anopheles funestus species subgroup, now accounting for 3,038 genomes.

To mark this milestone, here are three new visualisations of the data.

The first is a network depicting genetic relationships between mosquitoes from the Anopheles gambiae species complex. Each point represents a mosquito genome coloured by species. Each mosquito is connected to two other mosquitoes which are the closest in terms of genetic distance. The video shows an animation of this network being laid out using a force-directed graph.

I also created an alternative video showing the network using a different layout algorithm.

The second visualisation is a timeline showing when data releases where made available to contributing partner studies and how many mosquitoes each release contains. Data generation has accelerated particularly since 2020, thanks to support from the Bill and Melinda Gates Foundation and Wellcome.

The third visualisation is a map showing the geographical coverage of sampling locations in Africa. Each location is represented by a pie chart showing the number of samples by species. Data are available from 29 African countries, and a growing number of countries are now represented by longitudinal and subnational sampling.

A huge thank you to everyone who has supported and contributed to creating this data resource. So many people have gone to great lengths, overcome significant challenges and shown extraordinary patience, dedication and generosity to make this possible.
