A tidy_apriori object, rules object, or rules tibble

method

Visualization method: "scatter" (default), "graph", "grouped", "paracoord"

top_n

Number of top rules to visualize (default: 50)

...

  data("Groceries", package = "arules")
  res <- tidy_apriori(Groceries, support = 0.001, confidence = 0.5)
  visualize_rules(res, method = "scatter")
