When plotting huge data sets using Python while keeping interactivity, Datashader is paramount. In this post, I demonstrate the abilities of this powerful and convenient library. We use an unique dataset containing a whole year of shared bike usage in Cologne to plot over a million locations on a map.

Do you want to build map visualizations in Python? Look no further than GeoViews. It is not only super simple to use but also offers several interactive features that make your visualization stand out. Using geo spatial data from our bike rental data set we explore some of the possibilities.

Tinder is hugely popular and offers fascinating data on online dating. Still, there are barely any analysis of tinder data. In this endeavor we change that, by analyzing an unique dataset of tinder profiles. The data contains thousands of female and male profiles collected by swiping as a hetero- and homosexual male. Using descriptive statistics, visualization and natural language processing we uncover exiting patterns.

Including variables in a JupyterLab Notebook's Markdown cells seems like a basic thing. Turns out it is not. It's simply not yet supported out of the box. Here is how to do it anyways. Moreover, learn how to selectively hide code cells when exporting your Notebook. Improve the aesthetics and dynamic capabilities of your Notebook by using this simple approach.

Does the physicians rating platform Jameda discriminate against non-paying users? We investigate whether this claim made in an article by the newspaper "Die Zeit" can be supported.

In this multi part post, I will take a look at the bike rental system in Cologne. Following up on the previous work we start digging into the data using descriptive statistics. We look at some interesting findings and visualize them using matplotlib and seaborn.

Building on a basic choropleth map, we learn how to add additional interaction for the user. We visualize change in data patterns over time by allowing dynamic control over the plotted data. Moreover, we add animation to our visualization.

Using our bike data, we look at a different method to make a choropleth map. With the help of bokeh it is easy to create nice looking visualizations. They are interactive and can easily be integrated into web applications or websites.

Fahrrad Finder helps German users to quickly learn where the nearest sharing bikes are located.

Amazon has recently added an API for retrieving the location / address of an Alexa device. Learn how to quickly implement it using Python, and create new functionalities for your custom skills.

In this multi part post, I will take a look at the bike rental system in Cologne. In the first part we applied web-scraping and XML parsing to retrieve data and build a dataset of bike locations. Now, we will deal with geospatial tools and map visualization in order to search for interesting patterns in the bike-rental data.

In this multi part post, I will take a look at the bike rental system in Cologne. We’ll be dealing with web-scraping, XML parsing, GeoData and map-visualization in order to search for interesting patterns in bike-rental data. Lets get started with gathering the data!

There are a handful solutions for dealing with unconfirmed bitcoin transactions. However, depending on the case only a few of those might be viable. In this post, I describe how to apply the child pays for parent method in electrum. It is a solution that works most times.
