The Routine Health Information
Network (RHINO) connects people
around the world who believe we
can promote better health through
the use of information produced by
high quality, sustainable routine
health information systems.
For decades, health data has been
captured in dense ledgers & reports.

Handwritten tables and wall charts
were (and still are) common
monitoring tools.
Today, many systems have
gone digital.

Digital HIS expands the opportunities
to develop dashboards and other
visualizations of routine data.

other forms of visualization.

Invest (significant)
time in understanding
and exploring your
users’ needs.
Analytical ability
Job function
Education
Programmatic knowledge
Access to tools
Motivations to use data
Pain points
User personas are a tool we can use to understand who
the different users of a dashboard could be.

Map your data flow
Unique identifiers and
demographic data allow for
filters and dissaggregations.
Ensure the right users have
access to the right level of

1. Function: they let you
see trends and patterns
clearly.
2. Form: they are visually
appealing and well
structured to attract
readers and hold their
attention.
3. Integrity: they portray
the data accurately and
honestly.
4. Interesting: they are
relevant and
meaningful, or reveal
new information.

Facility 4 showed the highest quality of care.
Despite scoring highest, its overall score was below 50%, indicating there is
work to be done to improve quality of care across facilities.
Decluttered chart
eliminates the “non-
data ink” where
possible to focus on
the data story.
color strategically
Color used thematically for a set of charts representing
data on one topic.
Alert bar features red for indicators performing poorly
where action is required.
Promote accessibility by avoiding red-green maps and
charts that can be challenging for the colorblind.

Charts are titled with the
question they aim to
answer.

When designing, try sketching first
to develop a rough concept.
The visualization toolbox is
packed with options.
Remember to keep your user
front-of-mind when you pick your
