Example Help Request

"I'm using the `ggplot2` package to create a scatter plot. I
want to color points by a categorical variable, but the plot
isn't displaying as expected. Here's my code:

`ggplot(data, aes(x = var1, y = var2, color = category)) + geom_point()`

I expected each category to have a different color, but all
points are the same color. I've checked the variable
`category`, and it's a factor with three levels. What could
be causing this issue?"
