Currently Chart's visualChannel setup doesn't handle optional values within KeyPaths. For example, \.something that's a Double is fine, but one that's Double? isn't.

While messing around with CodableCSV, I found it useful to want to reference an optional property, with the goal of skipping the data if it returned nil, but that seems... to not be working at the moment.
