General Update Pattern - reusable: alphabet example D3v5+
This example demonstrates the General Update Pattern for reusable D3 charts, using a sequence of alphabet letters to show how data joins, updates, and exits are handled with `d3.join()` transitions. The visualization renders SVG text elements that animate vertically (entering from above, exiting below) while shifting horizontally as the dataset changes. Built as a reusable module pattern following ProD3 conventions, the chart uses `d3.transition` for smooth animations, with CSS classes for enter, update, and exit states. The code implements the updateable chart pattern from Rob Moore’s and Mike Bostock’s foundational work, using `d3.select` and SVG text manipulation.
