Chartograph Script was invented by Charles Smith, whose inspiration came from an episode of the cancelled Fox series Vanished. In it, a girl was taken in for questioning by detectives. When she was taken home in a squad car, she held her hand up to the window to show a message to the cameras, which detectives figured out was a Masonic script. More info on the script can be found in this image, and here.
Essentially, there are two charts to this alphabet, one looking like a tic-tac-toe board, the other looking like an X. Two letters are assigned to each spot, with one letter getting a dot to distinguish it from the other assigned to the same slot.
Charles adapted this to a consonant alphabet, as he considered it a natural way to represent voiced-voiceless pairs of obstruents. The idea of using letters for consonants and diacritics for vowels came from many abjads and syllabic alphabets, but mostly Arabic and Hebrew. The obstruents are contained on the tic-tac-toe board, with the sonorants on the X-type board. For example, a backwards capital 'L' represents /p/, while putting a dot in the middle represents /b/. As for the sonorants, Charles tried to pair sounds he thought were related in some way, with the two liquids /l, r/ paired, two of the nasals /m, n/ paired, the two semivowels /w, j/ paired and /N, h/ paired since they're in complimentary distribution. The vowel diacritics were inspired by abjads and syllabic alphabets from across the world, again largely by Arabic.
The script is mainly suited for English; it can be used with either British or American English, and probably other dialects as well. It could, in theory, be adapted to write other languages, but Charles hasn't done that to date. The name Chartograph was taken from the Greek morpheme -graphy "writing" and the fact that the script (consonants, anyway) are laid out in chart form.
