This visualization displays transactions from the Kvanto API, plotting daily transaction amounts in Danish kroner on the left axis and transaction counts on the right axis over time. It uses d3.scaleTime and d3.scaleLinear for the x and y scales, with d3.line generating the red and blue paths for each metric, while circles represent individual data points. The data is fetched via XMLHttpRequest, filtered by status, and aggregated using d3.rollup with d3.sum.
