The report requires a visual that shows how Sales changes over time (by quarter). A line chart is the most appropriate choice because: Purpose of a Line Chart: A line chart is ideal for visualizing trends and patterns over a continuous dimension, such as time (Quarter in this case). It displays the progression of values (e.g., Sales) across sequential periods. No Additional DAX Measures Required: Since the DAX measure already sums the Sales column, the line chart can directly use the measure for plotting the aggregated sales values against the Quarter field.
