if you made a filtered view of the table i guess you need to save it, because i see 2 copies of the original table with 20 463 rows

can we turn day numbers into text like sun and mon? you may want to convert this cell to JS and add a custom formatter on X encoding like tickFormat: weekdayScale, construct an ordinal weekdayScale() yourself with a known domain and range.

further challenge for you: can you make a picture where each order would be plotted so you can reveal some sort of a global pattern in the dataset? it's possible to do it with the chart cell without the code, but you would use pretty much all of the options you may need to have your dataset sorted and decouple pizza names and their sizes, thus adding an extra dimension. an example that the same data can be represented in different dimensionalities: [date, namesize, state] vs [date, name, size, state]
