This interactive visualization gallery presents a collection of chart types, including bar charts, pie charts, line charts, and scatter plots, all built using D3.js v5. Each chart is rendered as an SVG element and can be selected from a dropdown menu, with the underlying data displayed in a preview table. The example uses various D3 APIs such as `d3.scaleBand`, `d3.axisBottom`, and `d3.pie` to create the visualizations, with some charts featuring animation and tooltip interactions. Data is loaded from a CSV file and processed by the dashboard module.
