1.Thematic Heatmap Analysis
Digital Strategy Consultant · 2026
This heatmap visualizes the relationship between categorized user feedback themes and app store star ratings, solving a qualitative research consultant's challenge of manually coding large volumes of unstructured CSV review data. The chart plots seven distinct themes on the y-axis against 1-star to 5-star ratings on the x-axis, using a purple color gradient to indicate the percentage distribution within each theme from 10% to over 70%. By automatically structuring open-ended text into this interactive heatmap, the analyst bypassed labor-intensive tagging and revealed that 'Ease of use & lightweight design' drives 5-star reviews while 'Reliability & compatibility' concentrates in 1-star ratings.
What it shows:
Automated thematic categorization transforms unstructured text into clear, quantifiable performance drivers.
