You are designing a SQL Server Reporting Services (SSRS) report. The report must contain a chart that displays sales data for each product category over time. Sales data must be shown in the form of a

Scatter charts display the correlation or distribution between two numeric variables and are not designed to represent trends over a categorical time axis.

Line charts in SSRS map a continuous time axis to the x-axis and render each data grouping (product category) as a distinct series line, directly matching the requirement to show one line per category over time. This chart type is purpose-built for visualizing trends and changes across a time dimension with multiple comparable series. The result clearly shows each category's sales trajectory in a single chart view.

Pie charts show part-to-whole proportions at a single point in time and cannot represent change over multiple time periods or display separate category trend lines.

Range charts display data between high and low values to show variance or confidence intervals, not discrete per-category trends across a time series.
