What is role of data granularity in visualization?

< 1 min read

Data granularity defines the level of detail shown in a visual.
It determines whether data is displayed daily, monthly, or yearly.
Choosing the wrong granularity can mislead analysis.
In one project, daily sales data made the trend look volatile.
Switching to monthly granularity gave clearer business insight.
Granularity should match the business question.
High-level dashboards need summarized data, while operational reports may need detailed views.
Proper granularity improves clarity, performance, and decision-making accuracy.
