Coming from Python I tried to reproduce [this](https://seaborn.pydata.org/examples/spreadsheet_heatmap.html) Seaborn heatmap using Gadfly. The (only) issue I have is that the first and last columns appear smaller than the other columns. As a result the annotations are not fully readable. Is there an option to set all cells to “equal squares” or an other solution?

```julia
using DataFrames
using CSV
using Gadfly
using Compose
using ColorSchemes 

# download dataset
download("https://raw.githubusercontent.com/mwaskom/seaborn-data/master/flights.csv", "flights.csv");
flights = DataFrame(CSV.File("flights.csv"))

# prepare annotation
flights_unstacked = unstack(flights, :month, :year, :passengers)
x = [x for x in 1949:1960 for y in 1:12]
y = repeat(collect(1:12), outer=12)
txt = string.(Array(flights_unstacked[:, 2:end]))

# plot heatmap
set_default_plot_size(16cm, 12cm)
plot(
    flights, 
    x=:year, 
    y=:month, 
    color=:passengers, 
    Geom.rectbin, 
    Scale.ContinuousColorScale(palette -> get(ColorSchemes.magma, palette)), 
    Coord.cartesian(xmin=minimum(flights.year), xmax=maximum(flights.year)), 
    Guide.xticks(ticks=[minimum(flights.year):maximum(flights.year);]), 
    Theme(background_color = "white"),

    Guide.annotation(
        compose(
            context(), 
            text(x, y, txt, [hcenter], [vcenter]), 
            fontsize(7pt), 
            stroke("white")
            )
        ),
)

```

Commenting out the `Coord.cartesian` line solves the issue.
