Line chart! Shows trends, easy to read, perfect for daily sales over a year and the correct option is 3.
Jorge wants to understand daily sales over a year, which requires focusing on trends and patterns over time.
Line charts excel at showing trends and patterns over time, which is exactly what Jorge needs. Each day would be plotted on the X-axis, with the corresponding sales amount on the Y-axis. This allows him to easily see how sales fluctuate throughout the year, identify any peaks or dips, and analyze seasonal trends.
Line charts are simple and easy to understand, even for someone unfamiliar with data visualization. This makes them a good choice for Jorge, as he might want to share the insights with others who may not be data experts.
Other options are less suitable:
Heat maps are better for displaying spatial data, not time series.
Scatterplots with a categorical variable would be helpful if Jorge wanted to compare sales across different categories (e.g., product types), but not for analyzing daily trends.
Bubble plots are similar to scatterplots but add a third dimension (size) for additional data points. They could be useful if Jorge wanted to visualize another variable along with sales, but for a basic overview of daily trends, a line chart is sufficient.
Therefore, a line chart is the most effective and accessible visualization method for Jorge to understand daily sales over the year and the correct option is 3.
