This example demonstrates a smooth line chart built in Power BI, where a dataset of ten numeric pairs is generated and plotted as a continuous, curved trend. The visualization highlights how Power BI can transform raw tabular data into an aesthetically refined line graph using a custom data-shaping query. The underlying implementation relies on a Power Query (M) script that constructs a table with columns `a` and `b`, populating `b` with random numbers via `List.Accumulate` and `Number.Random`. The chart’s smoothness comes from Power BI’s built-in line smoothing, applied to the rendered series. This approach shows how simple data generation combined with native charting capabilities can produce polished, interactive analytics.
