(Labelled outliers) Video Game Publishers by Genre
This visualization displays video game publisher success by genre through a series of small multiples scatter plots, where each genre gets its own facet. The plots show the mean versus variance of global sales for each publisher within that genre. Outlier publishers are labeled directly on the chart with their names, using a z-score threshold to determine which points receive text annotations. The code uses Observable Plot within a D3 v6 environment, loading game sales data from a CSV file, and employs d3.rollup to aggregate the data by publisher and genre before computing mean and variance statistics.

This plot graphs mean vs variance in a set of small multiple scatter plots. I was considering doing a SPLOM, but wasn't sure how the trending would look at this time. Instead, I refactored this set of scater plots to contain labels on outlier data points.
To do this, I again used a z-score threshold to filter the variance of points, but this time, to include text marks on the observable plot.
As expected, many well-known game studios are listed in the outliers (such as Nintendo).
