line plot can not show more than 7 colors and if less than 7, all lines are connected.

[JunDamin]

When I plot more than 7 category as a color, it shows error as below. Also it shows wrong graph because all line connected which should be drawed by the region below 7 categories.

import TidierPlots, Random, DataFrames

region_names = ["A", "B", "C", "D", "E", "F", "G", "H"]
n_regions = length(region_names)
n_years = length(2010:2020)

years = repeat(2010:2020, n_regions)
regions = repeat(region_names, inner=n_years)
values = rand(n_regions*n_years)
df = DataFrame(year=years, region=regions, value=values)

(
    ggplot(df, @aes(x = year, y = value, color = region)) 
    + geom_line()
)

I think it should extends the number of colors or circulate colors automatically by default.
Also I think It should draw lines by its color not connected.
