There are countless ways to represent a place—neighborhoods, roads, waterlines, to name just a few. “But latitude and longitude are not the only dimensions that define a city,” says Nicolas Garcia Belmonte, a data visualization scientist at Twitter. “Whoever has biked in San Francisco, for example, can tell you the importance of knowing the topography of the city.”
Keeping the punishing hills of San Francisco in mind, Belmonte has created Andes, a three-dimensional, interactive look at where people in New York City, San Francisco and Istanbul have been tweeting from for the past four years. Belmonte used the same dataset that was developed for Geography of Tweets, an earlier project from Twitter’s Visual Insights team that visualized billions of geolocated tweets.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
