Explanation

A scatter plot (C) is ideal for observing the relationship between two numeric variables, identifying clustering patterns, and spotting outliers - each data point is plotted as a dot on an X/Y axis. A heat map (A) shows intensity or density across a matrix but doesn't plot individual data points clearly. A tree map (B) displays hierarchical data as nested rectangles. A stacked chart (D) compares part-to-whole relationships over categories or time, not the correlation between two numeric variables.
