Step-by-step explanation:
Selecting the most accurate statement regarding the use of color in data visualization reports or dashboards, color should be used to highlight important information and create visual hierarchy. This is because color can guide viewers to notice what is most important and help them to understand organizational levels within the data. Moreover, studies have shown that viewers display a preference for soft, muted colors rather than bright, garish ones, suggesting that color choices should be considerate of viewer comfort and comprehension rather than solely for aesthetic purposes or to make the visual interesting in a random way. Additionally, the use of color should always be meaningful and consistent, aiding viewers in discerning patterns and categories, as well as ensuring legibility and clarity in graphs and charts.
For completion, three kinds of graphs are pie graphs, bar graphs, and line graphs. Pie graphs are ideal for showing percentages of a whole and comparing proportions, bar graphs are useful for comparing quantities across different categories, and line graphs are best suited for tracking changes over time and trends.
