Generated using d3-ez D3 Reusable Chart Library
Punch Cards can visualize cyclical trends in your data. This visualization shows circles representing a metric aggregated over two dimensions, such as hours of the day and days of the week. Using a punchcard, you can see relative values for a metric where the dimensions intersect.
FUNCTION: Distribution; Trend over time
