A photographer friend of mine, Steve,
was commissioned to take pictures of
0:01
the Old Faithful geyser at
Yellowstone National Park in Wyoming.
0:07
For those not familiar with Old Faithful,
0:13
it is a cone geyser in Yellowstone with
a predictable geothermal eruption.
0:15
Steve hopes to take some amazing
pictures for his client.
0:21
He will be taking both still pictures and
video.
0:24
He would like to know the best
opportunities for taking still photos or
0:25
short videos of a single eruption.
0:30
I've discovered some data about
Old Faithful's eruption events.
0:33
It provides both the eruption time and
wait time between eruptions in minutes,
0:37
for 272 observed eruptions.
0:41
That's quite a few eruptions
to go through manually.
0:46
Let's see if we can but
our DataVis talents to use and
0:49
help Steve determine the best times
to take videos and still shots.
0:52
With all the different
chart types we've covered
0:56
which is the best tool
in our DataVis toolbox?
0:59
Based on Steve's business needs,
1:02
I think providing him with a few pieces
of information would be helpful.
1:04
One, the average time an eruption lasts,
so
1:09
he can determine how many memory
cards he'll need for his camera.
1:12
Or perhaps, he's going old school,
and old faithful, and using film.
1:16
Anyway, how long you should
expect to wait between eruptions?
1:20
And three, if there's a correlation
between the length of time of the eruption
1:24
and the wait time between eruptions.
1:28
This should help Steve know if he
should set his camera to video for
1:31
a short eruption or to plan on taking
still photos during a longer eruption.
1:34
Let's take a short break here,
1:39
let out a little steam and
think about charting techniques to use.
1:40
When we get back together we'd go
through my process for this project.
