Recently, I saw this chart on Economist website.
It is trying to depict how various cities rank on livability index and how they compare to previous ranking (2014 vs 2009).
As you can see, this chart is not the best way to visualize “Best places to live”.
Few reasons why,
- The segregated views (blue, gray & red) make it hard to look for a specific city or region
- The zig-zag lines look good, but they are incredibly hard to understand
- Labels are all over the place, thus making data interpretation hard.
- Some points have no labels (or ambiguous labels) leading to further confusion.
After examining the chart long & hard, I got thinking.
Its no fun criticizing someones work. Creating a better chart from this data, now thats awesome.
So I went looking for the raw data behind this graphical mess. Turns out, Economist sells this data for a meager price of US $5,625.
Alas, I was saving my left kidney for something more prominent than a bunch of raw data in a workbook. May be if they had sparklines in the file…
So armed with the certainty that my kidney will stay with me, I now turned my attention to a similar data set.
I downloaded my website visitor city data for top 100 cities in September 2014 & September 2013 from Google Analytics.
And I could get it for exactly $0.00. Much better.
This data is similar to Economist data.
Chart visualizing top 100 cities
Here is a chart I prepared from this data.
This chart (well, a glorified table) not only allows for understanding all the data, but also lets you focus specific groups of cities (top % changes, new cities in the top 100, cities that dropped out etc.) with ease.
Download top 100 cities visualization – Excel workbook
Click here to download this workbook. Examine the formulas & formatting settings to understand how this is made.
How is this visualization made?
Here is a video explaining how the workbook is constructed. [see it on our YouTube channel]
The key techniques used in this workbook are,
- SUMIFS, INDEX + MATCH formulas for figuring out data
- Sorting data by a particular column
- Conditional formatting to show % change arrows
- Form controls for user interactivity
Since the process of creating this visualization is similar to some of the earlier discussed examples, I recommend you go thru below if you have difficulty understanding this workbook:
- Suicides vs. Murders – interactive Excel chart
- Gender Gap chart in Excel
- Visualizing world education rankings
- Analyzing survey results with panel charts
How would you visualize similar data?
Here is a fun thought experiment. How would you visualize such data? Please share your thoughts (or example workbooks) in the comments. I & rest of our readers are eager to learn from you.

Pivot Table will involve manual intervention; hence I prefer to use the 'countif remove duplicate trick' along with 'text sorting formula trick; then using the offset with len to name the final range for validation.
if using the pivot table, set the sort to Ascending, so the list in the validation cell comes back alphabetically.
Hui: Brillant neat idea.
Vipul: I am intrigued by what you are saying. Please is it possible to show us how it can be done, because as u said Hui's method requires user intervention.
Thks to PHD and all

Table names dont work directly inside Data validation.
You will have to define a name and point it to the table name and then use the name inside validation
Eg MyClient : Refers to :=Table1[Client]
And then in the list validation say = MyClient
Kieranz,
Pls download the sample here http://cid-e98339d969073094.skydrive.live.com/self.aspx/.Public/data-validation-unsorted-list-example.xls
Off course there are many other ways of doing the same and integrating the formulae in multiple columns into one.
Pls refer to column FGHI in that file. Cell G4 is where my validation is.
Vipul:
Many thks, will study it latter.

[...] to chandoo for the idea of getting unique list using Pivot tables. What we do is that create a pivot table [...]
@Vipul:
Thanks, that was awesome! 🙂
@Playercharlie Happy to hear that 🙂
Great contribution, Hui. Solved a problem of many years!
Thanks to you, A LOT
Hi Hui,
Greeting
hope you are doing well.
I'm interested to send you a private vba excel file which i need to show detail of pivot in new workbook instead of showing in same workbook as new sheet.
Please contact me on muhammed.ye@gmail.com
Best Regards
