VISUALIZATION ENCODING

Each point is the light intensity for one seconde. Each line is a day.

VISUALIZATION INTERACTION

No interaction, visualisation is static.

html, css, javascript, d3.js, arduino, electronics.

STORY

Light sensor is shown over time, days and each seconds.

There is a lot of data points but we can see when the light is open during the night, or when i wake up...

Thats what is amazing with visualization: the user own the data context and add information to the visual one.
