Stacked-to-Multiples (improved)
This interactive visualization compares quarterly data across four groups, toggling between small-multiples and stacked layouts. Each group’s time series bars show raw values, with white text labels inside each bar indicating the group’s contribution per quarter, while the code accumulates these contributions into an array to reveal quarter totals. Using d3.v3, the example employs d3.layout.stack, ordinal and linear scales, d3.svg.axis, and transition.attrTween for smooth animated shifts between views. Data loads from a TSV file with date and value fields, rendered as SVG rectangles and text.
