D3 preview in RStudio does not render imported SVG

[mbacou]

I have an external SVG file circle.svg that I want to manipulate with D3.js:

<?xml version="1.0" encoding="utf-8"?>
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 161.4 39" style="enable-background:new 0 0 161.4 39;" xml:space="preserve">
<style type="text/css">
    .st0{fill:#C69C6D;stroke:#C69C6D;stroke-linejoin:round;stroke-miterlimit:10;}
    .st1{fill:none;stroke:#000000;stroke-linejoin:round;stroke-miterlimit:10;}
    .st2{fill:#C1272D;stroke:#006837;stroke-linejoin:round;stroke-miterlimit:10;}
    .st3{stroke:#C69C6D;stroke-miterlimit:10;}
    .st4{fill:#009245;stroke:#006837;stroke-miterlimit:10;}
    .st5{fill:#FFFFFF;stroke:#C69C6D;stroke-linejoin:round;stroke-miterlimit:10;}
    .st6{fill:#0000FF;}
</style>
<g id="anno_x5F_rect">
    <path class="st0" d="M141.9,37.5H19.5c-9.9,0-18-8.1-18-18v0c0-9.9,8.1-18,18-18h122.4c9.9,0,18,8.1,18,18v0
        C159.9,29.4,151.8,37.5,141.9,37.5z"/>
    <line class="st1" x1="19.5" y1="1.5" x2="19.5" y2="37"/>
    <line class="st1" x1="141.4" y1="1.5" x2="141.4" y2="37.5"/>
    <circle class="st2" cx="10.6" cy="19.1" r="5.2"/>
    <circle class="st3" cx="151.1" cy="19.2" r="6.7"/>
    <circle class="st4" cx="151.1" cy="19.2" r="5.7"/>
    <rect x="18.8" y="1.5" class="st5" width="122.6" height="36"/>
</g>
<g id="anno_x5F_text">
</g>
<g id="location_x5F_dot">
    <circle class="st6" cx="151.1" cy="19.2" r="5.7"/>
</g>
</svg>

The following code chunks work as expected in Rmarkdown (once the document is rendered), but I cannot preview anything in the D3 editor:

    ```{r, results="asis"}
    # Import D3
    htmltools::tags$script(src="https://d3js.org/d3.v6.min.js")

::: {#example}
:::

```{js}
const hw = $("#example").width();

var div = d3.select("#example");
var svg = div
  .append("svg")
  .attr("viewBox", [0, 0, hw, hw*0.8])
  .insert("svg:g"); 

// Append external design
d3.xml("circle.svg")
  .then(d => {
    svg.node().append(d.documentElement);
```

// !preview r2d3 data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20) // // r2d3: https://rstudio.github.io/r2d3 // var svg = svg .insert("svg:g");

// Append external design d3.xml("circle.svg") .then(d => { svg.node().append(d.documentElement); };

Thanks!
