📊 Interactive Data Visualization with Donut and Range Charts

This paragraph introduces a video on Tech mining, focusing on presenting sales data for different product categories in two distinct regions using interactive charting options. The video showcases a donut chart that allows viewers to hover over segments to see specific sales figures in US dollars. Deselecting items in the legend hides the corresponding data series, and clicking a legend item rescales the chart, which is beneficial for comparing series with significantly different values. Additionally, a link to page 6 is created for detailed product information, demonstrated by clicking on a bar representing 'Jr Phantom Vision', which drills down to page 6. The source code for these visualizations is available in the video description, and the process of creating these charts is outlined in a step-by-step approach.

🔍 Accessing Detailed Sales Data and Product Information

The second paragraph guides viewers on how to access the interactive sales data page within the application. It explains that by navigating to the 'Sales by Category and Product' card on the reports page, users can view two charts displaying graphical data for category and product sales. Hovering over the charts reveals sales figures, and deselecting items in the legend hides the associated data series. The paragraph also highlights the drill-down feature, where clicking on a specific product bar, such as 'Jr Phantom Vision', leads to page 6 for an in-depth look at the product details. The video concludes with a thank you note to the viewers.
