DiagrammeR How can I left align text in nodes using HTML

How can I left-align text in DiagrammeR::graphviz() when I use HTML code?

I need to insert bullet points, venus and mars signs into the nodes, and I have only been able to do this using HTML.

I can find several posts describing how to left-align when not using HTML (\\l), but I can't find any posts on how to do it using HTML.

How can I left-align the text in the nodes when using HTML?

Reprex:

```{r}
DiagrammeR::grViz("
digraph rmarkdown{

# Box
node [shape = box
     fontname = Helvetica,
     penwidth = 1.0,
     fixedsize = true,
     width = 3,
     height = 1]

A;

A[label = 
<
Top row<br/> 
&#8226; Bullet one<br/> 
&#8226; Bullet two with more words<br/>
&#9792; A venus sign
>]
}
")
```

Solution

  • I found an answer here: https://www.graphviz.org/doc/info/shapes.html

    You need to insert the line ALIGN = 'LEFT' in the HTML line break code.

    See below:

    DiagrammeR::grViz("
digraph rmarkdown{

# Box
node [shape = box]

A;

A[label = 
    <
    Top row<br ALIGN = 'LEFT'/> 
    &#8226; Bullet one<br ALIGN = 'LEFT'/> 
    &#8226; Bullet two with more words<br ALIGN = 'LEFT'/>
    &#9792; A venus sign <br ALIGN = 'LEFT' />
    >
]

}
")
```
