How to center text in an SVG region - svg

Question

I'm attempting to center the text in my SVG region but am not succeeding. Does anyone have any insight on how to optimize this?
<svg xmlns="http://www.w3.org/2000/svg" aria-label="Usa Mo" viewBox="0 0 70.389999 62.16">
<g>
<path tabindex="0" aria-label="Sainte Genevieve" fill="red" id="sainte genevieve" name="Sainte Genevieve"
d="m 57.466419,33.749401
2.854,2.605
-1.578,2.754
-0.463,-0.343
-0.441,0.418
-1.953,-1.762
-0.824,-0.796
1.293,-1.417
-0.982,-0.73
1.582,-1.112
0.512,0.383"
> </path>
<text font-family="Verdana" font-size="0.75" fill="blue">
<textPath href="#sainte genevieve" startOffset="50%" text-anchor="middle">Sainte Genevieve</textPath>
</text>
</g>
</svg>

The OP is commenting:
I just want the text to be inside the colored region and right side up.
In this case you don't need to use a textPath. You need to get the center of the path. For this you first get the bounding box of the path: let bb = thePath.getBBox()
Next you get the center of the path:
let x = bb.x + bb.width/2;
let y = bb.y + bb.height/2;
Finally you set the x and y attributes of the text as x and y making shure that the text is centered around this point: text-anchor="middle" dominant-baseline="middle"
let bb = thePath.getBBox();
theText.setAttribute("x", bb.x + bb.width/2);
theText.setAttribute("y", bb.y + bb.height/2);
svg{border:1px solid; width:300px}
<svg xmlns="http://www.w3.org/2000/svg" aria-label="Usa Mo" viewBox="50 30 15 12">
<path id="thePath" aria-label="Sainte Genevieve" fill="red" id="sainte_genevieve" name="Sainte Genevieve"
d="m 57.466419,33.749401
2.854,2.605
-1.578,2.754
-0.463,-0.343
-0.441,0.418
-1.953,-1.762
-0.824,-0.796
1.293,-1.417
-0.982,-0.73
1.582,-1.112
0.512,0.383"
> </path>
<text id="theText" font-family="Verdana" font-size=".75" fill="blue" text-anchor="middle" dominant-baseline="middle">
Sainte Genevieve
</text>
</svg>
Observation: I've changed the viewBox of the svg element because I wanted to have thePath in the center. You can change it back to what it was.
