| Wow. That's crazy.

| Genuine question: is this actually useful in real life, or just a

|
| Is producing elaborate charts in a terminal something people

|
| Edit: some fantastic responses. Makes perfect sense. Thank you!

| Julia also, but can take a few mins).

| You can copy and paste it right into the comments or

|
| That's one use case.

| Yeah, I find it super useful when you want a maximally quick

| hassle), using UnicodePlots can "break my flow" less than
| generating prettier plots in another window.
