Data Visualization in Environmental Public Health: From Data to Insight
Presenting Findings Without Context or Benchmarks
How to Make It Better Add a meaningful benchmark to help the audience interpret the trend. For example, a horizontal line showing an 85% program target would immediately show that compliance remained below the desired level during some of the years. • Clearly label the target or benchmark. • Keep the historical trend to show how performance has changed over time. • Add a brief annotation to highlight an important change, such as the decline in 2024 and any context about this change. • Use a descriptive title that communicates the key finding.
What’s Wrong with This Visual? The chart shows how inspection compliance changed over time, but it does not provide enough context to determine whether the results represent acceptable performance. • Viewers can see the trend but cannot tell whether the compliance rates met expectations. • No target, standard, or other benchmark is provided for comparison. • The decline from 88% in 2023 to 82% in 2024 is visible, but its significance is unclear without a reference point.
