A multiple-bar chart can effectively show how multiple variables relate to the primary variable by displaying each variable as a separate bar within the chart. It allows for easy comparison between the variables and their relationship to the primary variable. Line charts are better suited for showing trends over time, tables can be cluttered and difficult to interpret, and pie charts are best used for showing proportions.
