This visualization is an interactive dashboard that displays a single chart at a time, selected from a drop-down menu of eleven different chart types, including bar charts, pie charts, area charts, scatterplots, and a spectrogram. The dashboard generates charts using D3 v5, rendering with SVG and canvas, and supports an animated spectrogram that analyzes audio data. It uses D3 scales and axes, including `d3.scaleLinear`, `d3.scaleBand`, and `d3.axisBottom`, to map data from sample CSV files.
