One way to hold this word: the information stops being words and becomes a picture. Sometimes the picture is drawn on paper, in lines and bars. Sometimes it is built in the listener's head out of a few exact details. Either way the test is the same — after it, someone can see the thing instead of only being told about it.
可以想成這個畫面：資訊不再是文字，而變成一幅圖。有時候那幅圖是真的畫出來的，有線條、有長條。有時候它是靠幾個精準的細節，在聽的人腦中長出來的。兩種的檢驗方式一樣——結束之後，對方是「看見」了，而不只是「被告知」。
From the word’s history
The source's etymology tree gives the word as graphic plus -ally. The picture idea sits in graphic itself, and the adverb simply says that this is how something was done.
來源的詞源樹把這個字拆成 graphic 加上 -ally。「圖」的意思本來就在 graphic 裡面，副詞只是把它變成「用這種方式做」。
