It would exactly be like the bar graph where I can put a hex value.

Support the most important properties and add a generic function for adding any legend property

Just started using this awesome library, so maybe this is not an issue/bug, but me not knowing enough.

However, trying to order my bar chart by value of x, I use this function call. If I dump the output, the encoding options for x are put onto y (and the other way around).

Tucan.bar(distances, "year", "dist", x: [sort: "-x"], fill_color: "#33245A", corner_radius: 5, orient: :horizontal)

Include

• installation (both mix.exs and livebook)
• sample code
• acknowledgements

Add more themes and document the default themes. Move themes in exs files in the priv folder and auto-load them

Add dataset info in the keyword list and auto-generate the docs:

• url
• license / credits
• description
• columns info

Are there any 3D plots available like 3D scatter plots or planned to be implemented? I need one for a visualisation in Scholar.

The following plots should be included in the first version:

Single view plots

Check the items once the plots are fully implemented and documented

• line
• barchart
• countplot
• scatter
• bubble
• histogram
• heatmap
• density
• stripplot
• area
• pie
• donut
• boxplot

Composite plots

• pairplot

Are polar plots something that would be welcome here?
I have this PR open on VegaLite, but with the presence of this higher level library, it might be welcome here instead.

The only thing I'm not sure about is that the higher level API might not support the current structuring of the code.

Add helper functions for adding vertical and horizontal lines

Vegalight can take "container" as a value of width, height.
Tucan allows only integer for the value of sizes yet.

Add guides for using Tucan. Add here vega lite guides we can port to Tucan

vegalite has rounded edges for bar graphs as an option.

Add a function for adding marginal distribution plots to any graph with quantitative channels. The user should be able to select the type of the distribution plot.
