Submitting Your First Project
You did it! You’ve completed an entire unit of study. Congratulations on all the hard work–that took a lot of dedication. Only one step left, and that’s to complete and submit your first project. But the project submission screen contains quite a bit of information, doesn’t it? It might be tempting to jump right in and start working on your project, but I recommend slowing down and reading the instructions carefully first. In this workshop I’ll be covering some of the most important content from the Project One submission screen.Viewed
Data Visualization Foundations
What is data visualization? A simple answer might be something like the graphic representation of data. But to get a better understanding of what practitioners of data visualization do, let’s start with the term data. By data, I mean raw, unorganized facts and numbers. Practitioners of data visualization take raw, hard to grasp data and turn that data into information by providing context and a purpose.
