How can health facilities use data visualisation to improve health outcomes?

Simple visualisations are often more effective than complex ones. A clear bar chart showing monthly malaria cases compared to the same period last year is more actionable than a complex multi-variable analysis. Start simple and add complexity only when users are comfortable with the basics.

The key principle of effective data visualisation is to design for the audience. A dashboard for a facility manager should look different from one for a county health officer or a national policymaker. Involve the intended users in designing the visualisations to ensure they are relevant and actionable.
