The trendline matters. Focusing on a specific year is meaningless, which is what this visualization is trying to show. It's not trying to argue against mercury but against the annual headlines that there is a hottest year.
Your (I assume your, since your username matches the site) visualization shows a tree, and reads as there being 31800 wiped emails, of which 12200 were later found, and of those 2800 were work related. I'll quote FactCheck.org, one of the sources you list on your site:
>There is no evidence to date that work-related emails were intentionally deleted. ... In his July 5 press conference, Comey said “like many e-mail users, Secretary Clinton periodically deleted e-mails or e-mails were purged from the system when devices were changed.”
Your visualization states that the FBI found emails that Clinton wiped. This isn't the case (or at least, the FBI doesn't believe this is the case).
The racial killing one is misleading, although I'll grant you not explicitly false, just heavily misleading. Specifically, your use of percentages is badly phrased and could be seen to push a misleading narrative.
If I hover over raw, I see "6546 blacks killed by blacks". This is a true statement. If I hover over percentages, I see "92.9% of blacks killed by blacks". This is obviously not true, since it would imply that every black person was killed this past year, and 93% of them by other, now dead, black people, a ridiculous assertion. Instead, what you should state is "Of the ~7000 black people killed last year, 92.9% were killed by other black people". That's the true statement.
I don't claim this is false though, because it was obviously just a formatting mistake, which I hope you'll amend now that I've informed you of it.
It seems to me however, that you are trying to include something percentage based to imply that you're normalizing by population. That is, according to the census bureau, there are about 39 million black Americans, and about 224 million white Americans (I rounded both to the nearest million, which was up in both cases).
That means that a black American had a 258/39,000,000 chance of being killed by police, while a white american had a 666/224,000,000 chance.
Or in other words, 6.6 in every million black Americans was killed by police, and 2.97 in every million white Americans was killed by the police.
To put it another way, you're normalizing within groups instead of across groups, and this leads to a practically useless set of numbers that you can throw at people, but don't have any practical value. So even if you do change your formatting issue, it would be better if you showed the across group normalization, instead of what you currently have, which isn't a valuable piece of data.
Edit:
For someone who is quick to claim others are making mistakes "its all about the trendline" and "I'm tired of people making the current year being the hottest into something its not", I would expect better work honestly.
Thanks for taking the time to help improve things. I agree with some issues you raise but not others.
For the Clinton server, I never stated that work email being wiped was intentional. The fact is though that almost half of her emails were securely wiped with bleachbit, and the FBI recovered 5600 work related emails, of which at most half are duplicates of those turned over. I give the benefit of the doubt and list that half of them are new. See the WSJ source for the FBI stating that they found emails that Clinton wiped.
Homicides by race - you're right about the tooltip not being as clear as can be. I need to be terse so that the tooltip can fit on mobile, but I do mean the percentage to be detailing the size of the histogram slice.
I defend using the percentages instead of whole populations though. Looking at the total population is asking what kills people the most. Looking at a breakdown of homicides is asking who kills the most. It's a case of Simpson's paradox where the subpopulation does not conform to the aggregated whole.
I'm happy you expect good work out of the site - that's what I strive to accomplish.
>For the Clinton server, I never stated that work email being wiped was intentional.
No, but your graph shows that of the 30K emails that were deleted after the start of the investigation (with bleachbit, as you say), 2800 were work related. The FBI does not claim this, nor do your sources. It is as far as we know, a false claim.
>It's a case of Simpson's paradox where the subpopulation does not conform to the aggregated whole.
Its not, you are never combining groups. Its just a bad application of percentages (and perhaps a worse visualization).
We don't have a fully accurate measure of what the earth's temperature is, so scientists estimate what is it based on available data. Any temperature recording device also has an error margin. Thus the annual temperature is an estimate with a 95% confidence interval.
Per capita would hide lurking variables like differences in crime rate among different communities. Comparing to overall homicides surfaces this effect more.
