Exactly! I should probably have a section (or at least a link to a resource) that talks about _why_ you would want to learn this.
I have an image in the book detailing the spectrum of data viz tools on the web. At one end are the quick-pickup tools that aren't customizeable, and at the other end you have.. d3. Which isn't really a framework so much as a collection of tools that can help with making web charts.
What I probably failed to communicate in this post is that there are tons of opportunities to help communicate data with the web. Tooltips are just the most common interaction, but you could easily envision using scroll as a trigger, or adding a way to "zoom in" on parts of a chart.
The learning curve is definitely steeper, but once you have the skills, the world is really your oyster for visualizing data online. The pudding (https://pudding.cool/) is a great showcase of possibilities, or even uncommon chart types like at https://wattenberger.com/fishing
