I think researching statistical data is indeed time consuming especially if what you need is a simple chart to along with a sentence or two of your blog.

When even code can generated automatically nowadays, I think a writer tool which generates appropriate charts based upon the statistical data depending upon what you're writing could address this need-gap.

e.g. You are writing about TikTok and the tool automatically generates charts for TikTok user figures across different countries, screen-time etc. based on statistical data from Statista & other sources on the side bar. All you need to do is just click on them to embed into your content.
