A financial dashboard combines a temporal scatter plot and a time-series bar chart to analyze personal transactions, with linked selections across both views. The upper chart displays credit/debit amounts over time, while the lower plot correlates category, amount, and date. Built using D3.js v7 and Vega-Lite API within React, it renders via the `vl.vconcat` layout, reads CSV data from a GitHub gist, and includes interactive interval and point selection parameters for coordinated filtering.
