Hi, let's talk about numbers and data and how to make images from things like that so people can understand what the heck.
KNOW THY DATA:
the basic building block
all things flow from here.
numbers simply describe the world
let them.
making charts is not so hard, finding what to make charts of can be a great challenge.
what i do-
spreadsheets are how machines read- but terrible for us.
we (PEOPLE) are pattern recognition machines- show the patterns
a small piece of advice:
GARBARGE IN, GARBAGE OUT
a small piece of advice:
GARBARGE IN, GARBAGE OUT
formats- xls, csv, tsv, sql, shp,
the dreaded PDF
where to find-
government websites
specific websties for your topic
FIOA requests
ASK YOUR SOURCES
roll your own -

vs
data is plural - good resource
explore! start a folder, bookmarks, notes, etc
follow the trails- look at bottom for sources, everyone has data, assume they do until they tell you they don't
analysis-
for larger datasets, look for databases / ask for data dictionary- KNOW THY DATA
statistics = sexy.
don't kid yourself.
a few thoughts on interpreatation:
correlation is correlation.
causation is causation.
causation is usually (linear) correlation.
but C'MON NOW
correlation is not causation!
don't get crazy
tools:
excel,
googlesheets,
sql,
sublime text,
GIS
online what have you
google is everything.
watch for:
naming conventions, date formatting, number formatting, column names
states, business names, county names, FIPS codes
cleaning issues
make things uniform to save yourself pain.
a lot of this comes with massive amounts of repitition, knowing what to look for, the warning signs.
once you have your data ready, now comes the hard part-
what does it say? how to best present?
familiarize yourself with the range of charts-
presentation:
DO NOT BE TAKEN IN BY RAZZLE DAZZLE
good data makes an impact simply by it’s shape and the shape of it’s ideas.
if you have to explain why it’s good, it’s not good. it should present on it’s own.
people do not read charts!
never:
dual axis
bar charts always start at 0.
bar vs line- a common conundrum
it’s not always a map. think it's a map? it's probably not
pie charts- meh
hard to compare slices, overall size often done incorrectly.
(area not just radius = pi*rsquared)

your three part mantra:
data
analysis
story
all presentation decisions flow from these
ask yourself questions
when confronted with
head scratching
or hard decisions.
Then, as you would choose words and adjectives to frame ideas, you use colors and bars and lines and circles to clearly illustrate concepts with rigor and panache.
easy.

COLORS!
highlight one.
is it a MAP?
probably not.
BAR VS LINES
rate?
total amount of a thing?
percent change?

they are an entry point. eye magnets
make it count.
there are many details to consider.
type sizes-
fonts-
be simple.
simple
simple
reduce to the bare essence.
be poets.
Don't go on forever blathering about what ever nonsense you think is important, if it's not. ask the data what it needs to be and let it be that. if the data and your story aren't seeing eye to eye, let it go away. Then go find better data.
