This visualization pairs a scatter plot of transaction amounts by category with a time-series view of the same data, enabling linked filtering through interval and point selections. The top chart plots logged amounts against categories, while the bottom chart displays amounts over time from a CSV file of personal financial transactions. Built with Vega-Lite and D3, the charts use cross-filtering to highlight correlated selections, with tooltips showing amount, description, date, credit/debit status, and category.
