Diagrams 2020 is the eleventh conference in the biennial series that
started in 2000. The multidisciplinary nature of Diagrams means it
encompasses: architecture, art, artificial intelligence, biology,
cartography, cognitive science, computer science, education, graphic
design, history of science, human-computer interaction, linguistics,
logic, mathematics, philosophy, psychology, and software modelling.
The conference attracts a large number of researchers from these
interrelated fields, positioning Diagrams as the major international
event in the area.

Diagrams 2020 will be hosted by Tallinn University of Technology in Estonia.
Tallinn is the capital of Estonia and a beautiful seaside city. It has a well
preserved medieval old town which is listed as a UNESCO World Heritage Site.
The city is ideally located and designated for those who wish to explore
Estonia’s vibrant cultural life, digital society and natural sites.
Tallinn is easily accessible by flight from international cities, either
directly or by transiting through Helsinki (Finland) and Riga (Latvia).
