Elm-Vega Transform Tests

aggregation transform (should bin mean acceleration into engine cyclinder count)
bin transform (should create frequency histogram of IMDB ratings)
Similar but with bin steps of 0.25.
impute missing values when a=3 and c=1 by inserting b= mean of non-missing b values when c=1.
density transform of IMDB ratings.
loess transform to show trend overlaid on IMDB scatterplot
lookup transform used to link data table with geoJSON in choropleth.
pivot transform used to tidy data to show temperatures in 2017 for three cities.
quantile transform for uniform and nornal distributions.
regression transform to show 3rd order polynomial trend overlaid on IMDB scatterplot
Linear regression transform with coefficients and R-squared values displayed.
flatten transform to flatten nested objects.
fold transform for tidying data. Should produce two bar charts each showing US and Canada gold and silver medal totals.
stack transform to create mosaic (blue-orange-red from left to right and dark to light top to bottom.)
timeUnit transform to aggregate temporal data into month bins.
timeUnit transform to aggregate temporal data into 2-month bins.
timeUnit transform to aggregate temporal data into inferred month bins by specifying the maximum number of bins as 12.
Four time bins each of 5 minutes by setting the units to minutes and timeUnit step to 5.
window transform to sum values by category used to calculate proportion of total.
Should be identical to previous but uses joinAggregate transform.
