Coloring cities based on streetnames

Recently I saw this tweet from @puntofisso where he coloured the roads of urban areas mainly in England, based on their names. He got his inspiration from this article from @Erdavis and @cedscherer. I used and adapted his code that uses Osmnx for Python to create maps of Dutch cities, colored by their streetnames. Here’s Amsterdam:   The Canals are clearly visible, and besides that … Continue reading Coloring cities based on streetnames

Packed circles and treemaps from Flourish

I tried to use nested circles in a visual, using Flourish. A dataset about different types of roads in different cities in the greater Amsterdam area seems to lend itself for this type of visual. The viz below is easy to make in Flourish: But I did notice quite some flaws, that are issues with this type of chart. They are probably magnified by my … Continue reading Packed circles and treemaps from Flourish

Auto’s en toeristen snelst stijgende bron van inkomsten voor Amsterdam

Het CBS publiceerde een artikel over de gemeentelijke belastingen in Nederland voor 2019 met een aantal interessante inzichten. In het artikel wordt Amsterdam apart genoemd als het gaat over toeristenbelasting en parkeerinkomsten, daarom heb ik gekeken naar de bijdrage van deze posten voor Amsterdam. Dat blijkt behoorlijk anders dan het totale beeld van Nederland. Waar voor heel Nederland de Onroerendezaakbelasting op 1 staat, is dat … Continue reading Auto’s en toeristen snelst stijgende bron van inkomsten voor Amsterdam

The power of telling stories with data

“Most of us need to listen to the music to understand how beautiful it is. But often that’s how we present statistics: we just show the notes, we don’t play the music.” – Hans Rosling If you have never heard of Hans Rosling, now is the time to get to know his work. He’s one of my great heroes, because he turns statistics into amazing stories … Continue reading The power of telling stories with data

I … Continue reading Are your neighbours young or old?
