Calendar heatmap graph
This d3.js heatmap representing time series data is used to visualize tracked time over the past year, showing details for each of the days on demand.
Includes a global overview of multiple years and visualizations of year, month, week and day overview with zoom for details-on-demand.
Inspired by Github's contribution graph

Example data
Time series data where each day has a total time tracked (in seconds).
Details, if provided, are shown in a tooltip on mouseover in different overviews.
var data = [{
"date": "2016-01-01",
"total": 17164,
"details": [{
"name": "Project 1",
"date": "2016-01-01 12:30:45",
"value": 9192
}, {
"name": "Project 2",
"date": "2016-01-01 13:37:00",
"value": 6753
},
.....
{
"name": "Project N",
"date": "2016-01-01 17:52:41",
"value": 1219
}]
}]
Additionally you may specify a color to be used as the primary color for that data point in daily overview, for example:
var data = [{
"date": "2017-01-01",
"total": 18456,
"color": "red",
.....
}]
Optimization
In some cases details array could be large and in order to fit the data into the tooltip a short summary is generated with distinct projects and their total tracked time for that date. In terms of optimization, summary data can be computed server-side and passed in using the ``summary'' attribute. And in addition to the data structure described above this would result in a summary dictionary with distinct project names and total values of tracked time in seconds, e.g.:
var data = [{
"date": "2016-01-01",
"total": 17164,
"details": [.....],
"summary": [{
"name": "Project 1",
"value": 9192
}, {
"name": "Project 2",
"value": 6753
},
.....
{
"name": "Project N",
"value": 1219
}]
}]
