Most posts on this site are about statistics and programming. The posts contain math, plots and the code to reproduce the results. The code makes reading the posts more difficult. However, most statistical calculations cannot be done by hand. For example, fitting a linear model requires minimizing the sum of squares. By adding the code, this blog aims to show that statistical results are not created by some magical procedure.

For example, creating a plot can be done in a few lines of code:

```
using AlgebraOfGraphics
using CairoMakie
I = 1:30
xy = mapping([I] => :x, [I.*2] => :y)
draw(xy)
```
