Given the following dataset, which best communicates the sales data?
1) A line chart connecting vertices plotted with a vertical quantitative continuous sales axes and a horizontal quantitative continuous date axis.
2) A scatter plot of four disjoint datapoints plotted with a vertical quantitative continuous sales axes and a horizontal quantitative continuous date axis.
3) A bar chart were the height of four evenly spaced bars (one for each date) is plotted on a quantitative continuous vertical axis.
4) A bar chart in three-dimensional perspective, where the height of four evenly spaced bars (one for each date) is plotted on a quantitative continuous vertical axis, plotted such that the line of sight positions the earlier data in front and the later data further away.
