This scatter plot displays World Happiness data, mapping GDP per capita on the x-axis against flipper length on the y-axis. It uses D3.js and `viz.js` to render circles, with axis labels from `@curran/axis-labels`. The code loads data from `@mjmacgregor/worldhappiness`, featuring a grey inner rectangle and semi-transparent circles, though the y-axis value mapping appears counterintuitive for happiness data.
