This interactive lollipop chart displays four football statistics—Goals, Goals Conceded, Titles, and League Points—for the years 2008 through 2012. Clicking a button triggers the `update` function, which transitions the vertical lines and circle markers to new values using animated `transition` calls on SVG elements. The chart reads tabular data from a remote CSV file via `d3.csv` and scales axes dynamically with `d3.scaleBand` and `d3.scaleLinear`. Rendering is entirely SVG-based, with axis and glyph transitions handled through D3's selection and merge operators.
