 ## How to visualize the data
 
-The library can be integrated with various vizualisation frameworks. Below we show two example codes that can be a base for further exploration. The first example uses `folium`  via `PyCall` while the second example uses `Plots.jl` combined with [`OpenStreetMapXPlot.jl`](https://github.com/pszufe/OpenStreetMapXPlot.jl).

 ### Point of interest with Python folium via PyCall
 
 Below is a sample piece of code that can be used to generate a visualization of POIs on a map.
