I know it seems like a minor thing, but I'd prefer to keep the base style as unopinionated as possible. If a client wants this text centered there is already a way for them to accomplish that, as illustrated here:

wc-gocam-viz/src/styled.html

Lines 46 to 48 in 5c373a9

	wc-gocam-viz::part(legend-header) {
	text-align: center;
	}

@pkalita-lbl thanks, I have removed the styling

[tmushayahama]

@pkalita-lbl @kltm should we merge this?

For #37

Looks good to me

I've checked this on noctua-dev.

The legend now displays the 'provides input for' relation in my test model.

Noting, though, that the width of the relation in the pathway view still looks smaller than the other relations, and in bigger models, the lighter color of that relation can get lost as noted in:
#37 (comment)
#37 (comment)

We can deal with the display issue in separate work, as this PR does fix the legend, as requested.
