Det er fredag, tid til lidt sjov!
Her er en fascinerende måde at visualisere dine Google Analytics-data i en Trækortets visualisering, og du kan visualisere dine egne data med vores live demo.
(Bemærk: IE understøttes ikke i øjeblikket for visualisering del)
Målet med dette eksempel var at lære folk, hvordan du bruger Google Analytics-API på App Engine i Java. Såvel som viser, hvordan man bruger både OAuth og AuthSub sammen med App Engine's forskellige tjenester. Koden så stor, men resultatet var en kedelig HTML-tabel. Så jeg brugt nogle open source-værktøjer til at omdanne tabel i en smuk trækort visualisering!
Al den kode har været åben indkøbt på Google Project hosting. Jeg skrev også en artikel, der beskriver, hvordan dette program virker som gør det let for udviklere at bruge dette eksempel som udgangspunkt for nye data visualiseringer og andre Google-Data projekter.
Til læsning af data side bruger dette eksempel App Engine Java SDK og Google Analytics-Data Export API Java Client Bibliotek for at hente data fra Google Analytics. Eksemplet kode gennemfører både unsigned AuthSub og registreret OAuth tilladelse metoder gør det muligt for udviklere at komme op at køre hurtigt i udviklingsmiljøer og senere skifte til en sikker tilladelse metode i produktionsmiljøer. Ansøgningen bruger også Model-View-Controller mønster, hvilket gør det fleksibelt og giver udviklere at udvide koden for nye ansøgninger. (gerne tilføje understøttelse af andre Google-Data API)
For visualisering del plejede jeg at open source Protovis SVG Visualisering Bibliotek for at skabe Trækortets. Dette JavaScript-bibliotek er vedligeholdt af Stanford Visualisering gruppen og fremragende til at skabe helt nye visualiseringer fra et datasæt (i dette tilfælde en kedelig HTML-tabel). Til at håndtere alle de interaktioner, herunder rollover, tooltips og skyder kontrollerer, jeg brugte JQuery. Her er den JavaScript kilden til visualisering del af prøven.
Nyde!

PS Hvis du har oprettet en kølig nye visualiseringer ved hjælp af Google Analytics-Data Export API, e-mail os, så vi kan fremhæve dem.

Obesity
Obesity is when a person is carrying too much body fat for their height and sex. A person is considered obese if they have a Body Mass Index (BMI) - weight in kilograms divided by their height in meters squared - of 30 or greater. Obesity can happen when you eat more calories than you burn off over a period of time.
The rate at which you burn off calories from food and drink is known as your metabolic rate. This is often faster during growth spurts and puberty, but reaches a fairly steady rate by adulthood.
People who are very active generally have a higher metabolic rate than those who are inactive because they burn off calories faster through energetic activity. For example, a labourer working on a building site may need as many as 4,000-5,000 calories a day to keep an even weight. In contrast, an office worker who uses a car to get to work, and does not exercise, may only need 1,500 calories a day.
If the amount of calories provided by your daily food intake is more than the calories that you burn off, your body will store the extra energy as fat. This is the body's way of protecting itself in case of starvation. However, starvation in developed countries is extremely rare, and this insurance against 'hard times' is hardly ever needed.
Most of us have more food than we need, and much of it is higher in calories than the human body was originally designed to cope with. Fast foods, high calorie snacks, and large portions all mean it is easy to take in more energy than we need. Obesity has now become one of the most serious medical problems of the western world.
