Two D3.js v7 SVG charts display monthly data from ICE.csv. The first is a multi-series line chart plotting signups, revenue, and support tickets over time on a shared axis, using distinct pastel strokes and a legend. The second combines a bar chart of revenue with an overlaid line for support tickets, using shared time and value scales. Both charts employ d3.csv, d3.timeParse, d3.scaleTime, d3.scaleLinear, d3.line, and d3.axisBottom/axisLeft.
