What is the best graph to show retention rate?
A heatmap is the most effective visualization for retention rates since it uses color intensity to show patterns across cohorts and time periods at a glance. You can quickly create a retention heatmap for free using Graphy by simply pasting your data - no coding required. The darker colors instantly highlight which user groups have the highest retention, making it easy to spot trends and share insights with your team.

What are the best colors for a heatmap?
Single-color gradients like blue or purple work best for heatmaps since they’re colorblind-friendly and make it easy to spot patterns - darker shades naturally draw attention to higher values. Graphy automatically applies an accessible blue gradient to your heatmap, though you can easily customize the colors to match your brand.

What is the difference between a heatmap and a treemap?
A heatmap uses color intensity to show relationships between variables (like retention over time), while a treemap uses differently sized rectangles to represent hierarchical data proportions. For retention analysis and cohort data, heatmaps are the better choice - which you can create instantly for free using Graphy with just a simple data paste. While treemaps are great for showing part-to-whole relationships, heatmaps excel at revealing patterns across multiple dimensions.
