What are common challenges in implementing data visualization and how can they be overcome?

Almost any company that deals with large amounts of data could benefit from using data visualization tools. For instance, a retail company like Walmart could use these tools to visualize sales data. Line graphs could be used to track sales trends over time, stacked bar charts could be used to compare sales of different product categories, and dual-axis charts could be used to correlate sales data with other factors like marketing spend or seasonal trends. This would allow Walmart to make more informed decisions and strategies.

Line graphs are used to display data or information that changes continuously over time. They are most effective in showing trends in data at equal intervals or over time. Stacked bar charts are used to compare the total and one part of the totals of different categories. They are useful when you want to show the total size of groups, and how groups are divided into sub-groups. Dual-axis charts are used when two variables have different scales of measurement and they both need to be plotted on a single chart. They are useful when you want to compare two different measures with different scales.
