V2 Punchcard vis

The v2-Punchcard-visualisation app provides a custom visualization for Splunk that enables users to display metric density across two intersecting dimensions. The Punchcard visualization represents data points as circles sized proportionally to aggregated metric values, making it particularly effective for displaying cyclical patterns and trends. Common use cases include visualizing activity patterns across hours of the day and days of the week, identifying peak usage times, and analyzing temporal distribution of events. The visualization excels at revealing patterns in time-series data where both horizontal and vertical dimensions have significance, such as monitoring system load patterns, user activity trends, or incident occurrence across time periods. The app includes a gallery dashboard demonstrating the visualization's capabilities and typical configuration patterns.
