Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert $1 -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 $2

Results

This is a D3.js Heatmap example showing how the highest sun position of the day (which directly correlates with average temperature) changes over the year depending on the latitude of the place. The actual temperature chart would be shifted to the right a bit beacuse of thermal lag.

The data for the chart is calculated using SunCalc.

key	value	date
Group1	37	04/23/12
Group2	12	04/23/12
Group3	46	04/23/12
Group1	32	04/24/12
Group2	19	04/24/12
Group3	42	04/24/12
Group1	45	04/25/12
Group2	16	04/25/12

A sunburst is similar to the treemap, except it uses a radial layout. The root node of the tree is at the center, with leaves on the circumference. The area (or angle, depending on implementation) of each arc corresponds to its value. Sunburst design by John Stasko. Data courtesy Jeff Heer.
