To visualize data trends in Google Sheets, I typically use a variety of charts such as bar charts, line charts, and pie charts. These tools help in presenting data in a more digestible format. For instance, bar charts are great for comparing different categories, while line charts are useful for showing trends over time. I often start by selecting the data range I want to visualize, then use the 'Insert' menu to choose the appropriate chart type. Once the chart is inserted, I customize it by adding titles, adjusting axis labels, and using color coding to highlight specific data points. This approach not only makes the data more accessible but also aids in identifying patterns and insights that support informed decision-making.
