Problem embedding d3 as div

I recently made a post with a simple embedded d3.js chart. The simplest way to do this, as I understood it, was creating a div tag with an id, and using the d3.select("div#chart).append(“svg”) to embed the code. I also loaded the d3 library from its remote storage with a script tag inside the div. I understand this isn’t ideal, but I don’t think that was the cause of the subsequent problem.

When I added a new div, with a new id, it displayed correctly on my localhost. When I uploaded it to my site, however, the two charts were placed on top of each other. I could see no obvious reason why this would happen. I’ve recently disabled baseURL so my footnotes will work, but I didn’t see any reason that would cause the problem. The csv data files were still being found, etc.

Also, the current version of the post only displays one chart, as I deleted the other when I couldn’t get it working.

This was an issue with me reusing variable names and not the placement of the divs. I don’t know why it was displaying correctly on local host, however. Perhaps some type of caching.

I am new to hugo and am trying to accomplish what I think is a similar task but can’t seem to figure out how to get hugo to output a div with an id - I tried using a shortcode … and it compiles/builds but when I …

{{< viz class="ihaveclass" >}} 

shortcode …

<div class="{{ if .Get "class" }}{{ .Get "class" }}{{ else }}defaultclass{{ end }}">
  {{ .Inner }}
</div>

no div.

Pretty sure there is something fundamental I’m missing - but can you provide a small sample

I created the divs manually in html blocks in the original post. No shortcodes were involved, so I can’t offer any help here.

There are syntax errors with the way you use if and {{ .Get "class" }}

Something like this should work for you.

< div class="{{ if (.Get “class”) }}{{ with .Get “class”}}{{.}} {{ end }}{{ else }}defaultclass{{ end }}"

Can’t you get rid of the surrounding if statement and just use with since it’s more terse and tasteful?

You’re right. It’s superfluous.

This actually was just an issue with my being completely new to hugo and my custom layout was defined using

{{ define "main" }}
  {{ .Content}}
{{ end }}

instead of just

{{ .Content}}

I must have copy/pasted the layout from somewhere else as I have no theme and am using the victor-hugo boilerplate https://github.com/netlify/victor-hugo
