A basic bar chart can be created from a measure without requiring a dimension, making A correct. Tableau can construct an initial visualization automatically when a field is double-clicked in the Data pane. Official Tableau documentation demonstrates that double-clicking a quantitative measure such as Profit automatically adds it to the view and creates a bar chart. At this stage, no dimension is required; Tableau displays the aggregated value of the measure as a single bar. The remaining visualization types fundamentally depend on categorical partitioning. A highlight table uses dimensions to establish the table's row and column structure and measures to encode values through color or text. A treemap normally requires one or more dimensions to define individual rectangles, with measures controlling properties such as size and color. A stacked bar requires a categorical field to partition a bar into multiple stacked segments. A dimension can certainly be added later to a basic bar chart—for example, Category on Columns and Sales on Rows—to produce multiple bars. However, the question asks which visualization can be created without a dimension. Tableau's official field-dragging documentation specifically demonstrates that double-clicking a measure alone produces an automatic bar chart.
