What's included in this course?
To start, get to know Gemma Busquets better. She tells you about some of the clients she's made data visualizations for. She also shares her influences and books that have inspired her on a daily basis.
Next, she explains why data visualization is so present in our lives. Then see the key concepts that you should know before starting work, and the most common mistakes in order to avoid them.
Now delve into the three most popular graphic charts—bar, line, and pie. Take a look at who created them, before Gemma shares guides so you can use them without making mistakes. Also explore a range of other visually striking charts, maps, and diagrams.
It's time to hone in on the details! Your teacher teaches you about color palettes and how to improve typography. In addition, come to understand the importance of composition to use the space properly.
After laying the foundations of your final project—the theme, focus, objective, target, and medium— continue by defining the narrative to present the data and do sketches by hand. To wrap up the course, work with different tools to create and edit the graphics, as well as prepare your pieces for three formats—Instagram, a poster, and Power Point.
