Forked from D3 Course Code Along - Temperature Area Chart
This D3 code along demonstrates the general update pattern for animated data visualizations, using a row of colored circles that represent a fruit bowl. The example shows how to add, remove, and modify data items while maintaining object constancy through data join keys. Using the d3 v5 API, the code leverages selection enter, merge, and exit transitions with `transition.duration` to animate circle radius, position, and fill color over one-second intervals. The visualization cycles through scripted state changes, including removing an apple, changing a fruit’s type from apple to lemon, and filtering out another apple, all within an SVG canvas.
