D3 Examples - Respond to resize

Respond to resize
The data comes from the World Happiness Report. Direct link to the data download can be found here.
The work for this block was developed locally using Curran Kelleher's dataviz-project-template as a starting point and also used the block World Happiness Ranking.
The focus of this block is to scale both the chart and axes to take up the full screen. We do not maintian view ratio. We scale for width and height individually. Note that as the chart gets bigger the circles in the scatter plot get bigger, same with axes fonts and chart padding for the axes.
