+## Distribution plots
+
+Tucan provides several plot types for displaying the distribution of a numerical variable. Let's start by plotting the boxplots of the `temp_max` for the various `weather` types.
+
+```elixir
+Tucan.boxplot(:weather, "temp_max", group_by: "weather")
+|> Tucan.color_by("weather", scale: [range: color_palette])
+|> Tucan.set_width(500)
+```
+
+We could also use `Tucan.errorbar/3`.
+
+```elixir
+Tucan.errorbar(:weather, "temp_max",
+  group_by: "weather",
+  points: true,
+  ticks: true,
+  extent: :ci
+)
+|> Tucan.color_by("weather", scale: [range: color_palette])
+|> Tucan.set_width(500)
+```
+
+Similarly we could use `Tucan.stripplot/3` this time encoding the `temp_max` on the *x-axis*. Notice that we use `uniform` jittering.
+
+```elixir
+Tucan.stripplot(:weather, "temp_max", group_by: "weather", style: :jitter, jitter_mode: :uniform)
+|> Tucan.color_by("weather", scale: [range: color_palette])
+|> Tucan.set_width(500)
+|> Tucan.set_height(300)
+```

 ## Weather heatmaps
 
 A heatmap uses color to encode the magnitude of a value.

+### Showing the confidence interval
+
+We can use `Tucan.errorband/4` to plot the confidence interval. We also color by the weather type in order to display the max temperatures intervals by weather type.
