Question 1 of 30
A data analyst is tasked with visualizing the sales performance of a retail company over the past year. The analyst has access to monthly sales data segmented by product category. To effectively communicate trends and comparisons, the analyst decides to use a combination of visualizations. Which approach would best facilitate the understanding of both overall sales trends and category-specific performance?
Create a line chart to show overall sales trends over the months, and use a bar chart to compare sales across different product categories for the most recent month.
Use a pie chart to represent the percentage of total sales by product category for each month, and a scatter plot to show sales trends over time.
Develop a heat map to illustrate sales performance by product category and month, while also including a stacked area chart to represent total sales over the year.
Implement a single bar chart that displays total sales for each product category without any time dimension, supplemented by a table of monthly sales figures.
