Let's say you embed an interactive chart either using one of those JavaScript libraries from Google or another company. Can Google interpret the chart, since the chart has data within it and users can interact with the chart? The answer is not currently, but it is an interesting question I never heard before.
John Mueller of Google said Google treats "them mostly like images." He added "we don't read / interpret the content."
Wouldn't it be cool if Google could read those JavaScript based charts? Maybe even take your pretty charts and use them in their featured snippets? Oh, maybe that doesn't sound so good now?
In any event, it might make sense that if you want Google to see the content in the chart, to translate those data points in a table format and maybe in readable human paragraph blocks?
