Hi,

You could call DiagramItem.setSelected(true) to select initial node.

If using ShapeNodes you could set their EnableStyledText property to wrap long words - but it also parses some html tags for fonts and colors and formats the text.

If not using ShapeNodes or you prefer not to parse and format the text, you could replace MindFusion.Drawing.Text.wrapLine function with your own version that will also split long words:

var originalWrapLine = MindFusion.Drawing.Text.wrapLine;
MindFusion.Drawing.Text.wrapLine = function (context, text, maxWidth, lines)
{
	originalWrapLine.apply(this, [context, text, maxWidth, lines]);
	for (var i = 0; i < lines.length; i++)
	{
		var line = lines[i];
		var w = context.measureText(line).width;
		if (w > maxWidth)
		{
			var c = 1;
			var fittingPart = "";
			do
			{
				fittingPart = line.substring(0, c);
				w = context.measureText(fittingPart).width;
				c++;
			}
			while (w < maxWidth);
			var remaining = line.substring(c - 1);
			lines[i] = fittingPart;
			if (remaining != "")
				lines.splice(i + 1, 0, remaining);
		}
	}
}; 

I hope that helps,
Stoyan
