Local Regression in Python
I love data visualization make-overs (like this one I wrote a few months ago), but sometimes the tone can be too negative (like this one I wrote a few months ago). Sarah Leo, a data journalist at The Economist, has found the perfect solution: re-making your own visualizations. Here’s her tweet.... Read more
A New Method of Data Mapping – Dimensionality Reduction + Network Theory
When you visit a new place, probably you will rely on a map to guide you from place to place so you could get yourself oriented and help you find the most interesting places. The same happens with data. When you get a new dataset to work with, what... Read more
Interpretable Knowledge Discovery Reinforced by Visual Methods
Editor’s Note: See Boris Kovalerchuk’s talk “Interpretable Knowledge Discovery Reinforced by Visual Methods” at ODSC West 2019. Visual reasoning and discovery have a long history. Chinese and Indians had visual proof of the Pythagorean Theorem in 600 B.C. before it was known to the Greeks. Scientists such as Bohr,... Read more
Data Visualization for Academics
One of the reasons I am excited about the rise of data journalism is that journalists are doing amazing things with visualization. At the same time, one of my frustrations with academic research is that the general quality of visualization is so poor. One of the problems is that... Read more
Creating Multiple Visualizations in a Single Python Notebook
For a data scientist without an eye for design, creating visualizations from scratch might be a difficult task. But as is the case with most problems, a solution awaits thanks to Python. Those drawn to using Python for data analysis have been spoiled, as more advanced libraries have made... Read more
3 Things Your Boss Won’t Care About in Your Data Visualizations
Data Visualization is a critical part of your job as a data scientist, but it does require a bit of skill and a bit of intuition. Visualizations have incredible power to both inform and obscure, so getting the fundamentals of visualization down is a foundational data science skill. When... Read more
Introduction to R Shiny
Alyssa is a speaker for ODSC East 2019 this April 30 to May 3! Attend her talk “Data Visualization with R Shiny.” What is R Shiny? Shiny is an R package that enables you to build interactive web apps using both the statistical power of R and the interactivity... Read more
Data Visualization and the Data Science Workflow
If you think you can get away with poor communication skills as a data scientist because the data will speak for itself, Dr. Lindsay Brin is here to tell you otherwise. She believes that learning how to communicate data through proper visualization is critical for data scientists and outlines... Read more
Advantages and Best Uses of Four Popular Data Visualization Tools
Data visualization tools vary widely in their capabilities, required skill sets, and uses. While some platforms are easy to use, they oftentimes can’t communicate complex, multivariable data the way that tools with a little more complexity can. Here, we compare four popular visualization programs and their advantages, disadvantages, and... Read more
Data Visualization – Part 3
What Type of Data Visualization Do You Choose (if any)? Determining whether or not you need a visualization is step one. While it seems silly, this is probably something everyone (including myself) should be doing more often. A lot of times, it seems like a great way to showcase the... Read more
