Output
Returns a time-series dataset of cumulative total Bitcoin transactions, including timestamps and values. In JSON mode, may include metadata about the chart. In CSV mode, returns two columns: timestamp and value. Supports rolling average smoothing over configurable windows (e.g. 8h, 24h) and optional sampling to reduce data point density.
