Pyramidenkogel

I visited the Pyramidenkogel in Maria Wörth in Austria this summer. It is the tallest wooden observation tower in the world at a height of 100 metres. The photo above was made from the top with my Pentax KX with a 135mm f3.5 on Fuji Superia 200.

The cool thing about this tower is that there is an embedded 66 metre long slide in it, making the tower not only the largest wooden observation tower in the world, but it also has the longest slide in Europe!




This picture was also made with the KX on Fuji Superia 200, with my 28mm f2.8 lens. The KX is a joy to use and the Pentax M lenses give really good results. Looking through a lens made the heights a bit less intimidating. But the wonderful view is really worth the long climb. If you're near the Wörthersee, pay the Pyramidenkogel a visit!

Plotting graphs using python-igraph

First we include igraph and numpy:
Next, we create a graph by specifying the vertices and edge pairs:
Now we can apply styling to better visualize the data. We can, for example, scale the vertices based on their (out)degree, and color them accordingly:
We can also add the calculated (out)degree to the label of the vertex: Furthermore, we can set the edge weights based on the communities detected with community detection:
To make the graph look somewhat nicer, apply a little bit more styling:
Finally, plot the graph:
The final diagram now looks like this: The full code can be found here, more examples can be found here.
