D3 Example
This visualization displays sales data across product sub-categories, segmented by customer type (office, home, consumer) as three colored lines. The chart uses D3.js v3 with an SVG rendering approach, employing `d3.svg.line`, `d3.scale.linear`, and `d3.nest` to group data from the CSV file. Axes are formatted with a custom SI tick formatter, and a categorical color legend is generated using the d3-legend plugin. The interactive rendering responds to the loaded dataset, drawing one path per segment.
