PCA visualisation of embedded H3 Influenza virus sequences. An embedding of 3994 GenBank haemaglutinin sequences from H3N2 influenza viruses, generated using mBed, and visualised using the first three axes of a PCA of the embedded vectors. Each sequence has been coloured by year of isolation to show the progression of sequence change between the years 1967 (blue) and 2008 (red).
