This example visualizes quarterly sales of electronics brands in 2022 as a 3D bar chart, using the `d3-x3d` library to render interactive X3D scenes. The chart maps brand names along one axis and quarters (Q1–Q4) along another, with bar heights representing sales figures from embedded CSV data. It leverages d3.v5 APIs such as `scaleLinear`, `axisLeft`, `axisBottom`, and `csvParse` to process and scale the data, while the `d3.x3d.chart.barChartMultiSeries()` component constructs the 3D visualization within an HTML page using CSS for layout.
