This visualization presents customer data from a CSV file through two Plotly charts. A multi-series line chart displays trends in annual income, spending score, and satisfaction rating across customer IDs. A combined bar and line chart compares store visits (bars) against online purchases (line) using dual y-axes. The code uses the Plotly.js library, loading data via `Plotly.d3.csv` and rendering charts with `Plotly.newPlot`.
