This scatter plot visualizes the relationship between year and average temperature for China using the Climate Dataset, with each circle representing a data point. A dropdown menu lets users select a specific year, although the current rendering only displays China’s full time series. The visualization uses D3’s `scaleLinear` and `axisLeft` to construct axes, while custom label helpers from `@wyy-47/axislabels` add axis titles. The `viz` function draws a gray inner rectangle and semi-transparent circles with `selectAll` and `join`, updating the SVG directly.
