Which TWO visualization types are suitable for showing the distribution of a single continuous variable?

You are a data analyst for an e-commerce company. Your team has built a dashboard to monitor daily sales performance across five regions: North, South, East, West, and Central. The dashboard includes a bar chart showing total sales per region, a line chart showing daily sales trend over the past 30 days, and a pie chart showing sales distribution by product category (Clothing, Electronics, Home, Books, Sports). Recently, stakeholders have complained that the pie chart is hard to interpret because the Sports category has very small sales and is barely visible. Also, the bar chart uses a rainbow color scheme that makes it difficult to compare bar heights because the colors are not ordered by magnitude. The line chart is fine. You need to redesign the dashboard to address these issues. Which combination of changes is most appropriate?

You are a data analyst at a logistics company. You have created a dashboard to monitor delivery performance. The dashboard includes a scatter plot showing delivery time (hours) vs. distance (miles) for each delivery, with points colored by delivery region (A, B, C, D, E).

Additionally, the color legend for the five regions uses similar shades of blue, making it difficult to distinguish which region a point belongs to. You need to improve the scatter plot to reduce overplotting and improve region differentiation. Which approach is most effective?
