📊 Interactive Sales Charts Overview

This paragraph introduces the video's focus on creating interactive charts to represent category sales across different months. The video will demonstrate how to utilize a region display selector to toggle between two views of sales data. Viewers can hover over charts to reveal sales figures and click legend items to hide or show specific data series. The script also mentions the creation of a second chart displaying monthly sales data in a bar format, with tabs for viewing sales by category, line, or month. The 'Show All' tab is highlighted for its ability to display all regions at once. The process includes creating a blank page and setting up regions for the charts, with one region displaying other regions as horizontal tabs and another holding a line with area chart type. The script also discusses properties for rendering the chart data in chronological order and customizing chart appearance, such as markers and labels.
