Wonderful writeup, as always. One question on semantics, though. On sites like The Verge, there are usually grids of articles laid out in a very table-like style. While you say that tables should only be used for tabular data, I argue that layout like this is in fact tabular data. The convention rarely appears outside of blog homepages, but it does in fact perform the original function of a table: to lay out value in a visually-organized manner.
Complex content images, such as illustrations, diagrams, and charts, require more lengthy descriptions than can be included in an alt attribute. In many cases, the best approach is to include a caption with the image, which benefits all users in comprehending the information contained in the image. For example, for a chart that shows lifespan increase over time, include the data in an accessible table with the image. That way screen reader users have access to the same information, and people who comprehend numbers better than visualizations also benefit. HTML5 provides the and elements to make a programmatic connection between image and caption.

In this age and times of Technology and Big Data, Data visualization is increasingly becoming an absolute must-learn skill. As organizations become more and more data driven, not only do we need to interpret large amounts of data, but also be able to analyze, explain, digest and compare complex data in a manner that it is accessible to anyone who needs understanding of that data.
Also because of the way our human brain processes information, visually-displayed data in the form of charts or graphs etc is easier to understand than sets of spreadsheets and reports. A well thought out visualization peels back the layers surrounding a raw dataset. All businesses these days are therefore leveraging Data Visualization to analyse information faster, recognise patterns and trends, and find valuable insights. Organizations of all sizes are looking for Data Visualization experts. So the ability to work with data is not just a bonus skill, but an essential one, in fact it is the highest ROI skill in current times.
Data Visualization is not just limited to the field of data scientists and data analysts, in all careers whether finance, marketing, tech, design, etc. there is a need for data communicators who can visualize data and convey results effectively to both technical and non-technical people.
