The Temperature of My Mind is a data visualization that rendered hyemi's emotions across 426 diary entries. Using a thermometer as its central metaphor, each emotion was represented by its own unique coloring and intensity. All diaries were classified into four emotions: happy, gloomy, angry and wishful; and hues: yellow, gray, red and brown. Each hue was divided into three variables of brightness along with the strengths and weaknesses of the emotions.
