This repository contains a collection of graphics I have been working on with the aim to learn how to make fancy visualizations using R. Used data covers a variety of topics.

The first plot is a streetmap. I bet you have seen such pictures as elements of decoration and you may have even thought of buying one yourself. Well, I here show you how I made a NYC streetmap for myself following this tutorial and using OpenStreetMap database. Below you can see the final result. As said, this was NYC but you can just use any other spot you like in the world. Besides, you can easily customize the design elements with some notions of ggplot2.

This time I am doing a radar chart, also known as spider or star chart. According to Wikipedia, this chart consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points. A line is drawn connecting the data values for each spoke. This gives the plot a star-like appearance. Here I will be plotting the macronutrient composition of the most common cereals. I’ll obtain food information from the Spanish Food Composition Database (BEDCA) using the NutrienTrackeR package. For the chart I’ll be using the radarchart package, which provides an interface to the radar chart making function within Chart.js Javascript library. Now you can choose the best cereal for your own needs at a glance!
