Hey everyone! I’m at a bit of a loss as to why I’m encountering this problem. I’ve created a notebook using Bostock’s new TimeChart. I’m getting no errors and, even more bafflingly, the auto-generated thumbnail works. But the chart itself is blank in the notebook; I’ve checked in other browsers in the off chance I was blocking something, but no luck.

The draft is here: [https://observablehq.com/d/4fb9b3d6298ee059](https://observablehq.com/d/4fb9b3d6298ee059)

Is there something I’m overlooking that’s causing this? Thanks!

Hi @hepplerj, it seems like TimeChart is expecting UTC intervals formated data,

replace

```auto
parseDate = d3.timeParse("%Y")

```

with

```auto
parseDate = d3.utcParse("%Y")

```

Ah, of course it was something simple. Thank you!
