As other users said, a tool to create charts and graphs inside InDesign should be already featured years ago.
It should be enhanced compared to the one in Illustrator which has never be improved through the years. It would be great to have more type of charts and data entry and style adjustments for the chart should be made simpler.

In the near future more chart types will be available.

Easy UI for setting spider diagrams up – come on, it's 2021.

Totally agree. This is long overdue. I've just spent over an hour trying to figure out how to use Illustrator's graph feature. It is awful! Overlapping labels? Why on earth aren't there options to style everything as you go? I hate the way each of the Adobe CC applications use totally different ways of doing things. It makes switching between them disruptive and frustrating.

Please add this feature. It's been requested for years now.

Datylon offers an advanced dataviz extension for Illustrator to create RGB/CMYK charts. Check it out at https://datylon.com/graph. The charts can easily be embedded in Indesign

Next quarter we'll have an online chart editor as well that allows you to design advanced branded charts online. These charts can be downloaded as SVG/PDF for import in Indesign.

I use DeltaGraph for graphs, then export to then import into InDesign. What is a better way? I need the graphs for classroom lessons (bar, pie graphs). DeltaGraph is getting out of date. I looked at Numbers -- does not do graphs for page layout. What to do? I do not use Illustrator at all. Does Illustrator have graph design? Is it complicated? DeltaGraph is very easy!

I would love it if InDesign had a simple graph feature. It would be fine if it wasn't as robust as one in Illustrator, but it would really help with page design. Especially when you just need something simple.

As noted by Neat, support for improving the feature in Illustrator (Improve Graph / Chart tool) is growing and Adobe's engineers have been asking questions. I would suggest supporting the request for improvement in Illustrator or for a stand-alone app on that forum rather than pushing its inclusion in InDesign. With the improvements requested, linking and updating in InDesign wil be much easier.

Momentum seems to be picking up for this over on the Illustrator feature request forum; there's conversation about whether to include it as part of Illustrator or whether it's better to make it a standalone app.

Frankly, I'm a fan of the latter. Charting is a complex enough arena that it could easily encompass an entire program. I think folding it into another program (whether Illustrator or InDesign) leaves it vulnerable to neglect in favor of core features, which is why we've gone years without any updates to the current Illustrator functionality.
