  Effective decision-making for crisis mitigation increasingly relies on
visualisation of large amounts of data. While interactive dashboards are more
informative than static visualisations, their development is far more
time-demanding and requires a range of technical and financial capabilities.
There are few open-source libraries available, which is blocking contributions
from low-resource environments and impeding rapid crisis responses. To address
these limitations, we present SeismographAPI, an open-source library for
visualising temporal-spatial crisis data on the country- and sub-country level
in two use cases: Conflict Monitoring Map and Pandemic Monitoring Map. The
library provides easy-to-use data connectors, broad functionality, clear
documentation and run time-efficiency.
