The chart only has diacritics below letters at the moment. Because some letters have descenders, like [ŋ], the above-the-letter diacritics should be added: [ŋ̩] should be [ŋ̍]. Similarly with the voiceless symbol, retraction diacritic, etc. Most of these are available as Unicode characters and can be found by searching on unicodelookup.com using the names of the below-the-letter diacritics.
