My first experiment with data visualisation for journalism -- please review

[Ravi Bajpai]

Hi all,

Many of you don't know me, I joined the group only a month back. I am a journalist interested in exploring data visualisation for storytelling. I have made my first data visualisation with data on rainfall in India over last century. I would be grateful if you could see it and give me your feedback. Your views will really help me improve on this!

Thanks for the feedback Satya! I think we forgot to link the pdf file on some of the hyperlinks. I have got it fixed, you can download the data from any of the links.

Thank you again!

this is cool. :-).

On the Rainfall Tracker, it would be good to have the LTA (as a line) to compare.

How about circles/dots instead of the bars?

Hi Mahroof,

Thanks a lot for the feedback. Sorry, I didn't understand 'LTA', could you explain? You are right, I think circles might have been a better, neater option. 

Thanks again!

Good work Ravi!

Good use of the Tableau. The graphs are pretty interesting, especially the erratic rainfall graph. 

I might be interesting for you to pull out the most striking patterns for a close up. But a good effort overall. 

Is this the 100 year district data? Or Grid?  Did you get it directly from IMD? Are they allowing you to share it?

Hi Nisha,

Thanks for the feedback! You are right, I also feel I should have highlighted a few trends with close-ups. I work for the Centre for Science and Environment, one of our correspondents had a pdf file of the rainfall data, he shared it with me. Are you able to download the date from our page?

Thanks!

Thanks!

Actually India Water Portal has the dataset here: http://www.indiawaterportal.org/metdata

I have the files also if anyone wants the full set in excel.

Clarification our dataset is not directly from IMD but from a British NGO that RTI'd the data from the IMD then did analysis. So it is a little removed. If your dataset is directly from IMD could be a good comparison with our data.

Nisha

[Ravi Bajpai]

Thanks Nisha. It would be very interesting to compare the data sets. I'll check your data and compare 

[Ma-roof M]

Hi Ravi,

LTA is the long term average. I think it can be calculated over a period of 30 or 40 or 50 or 100 years (not sure).

IMD calls it the LPA (Long Period Average) and is calculated over a period of 50 years between 1951-2000 (I could see 1941-1990 used somewhere. I wish someone could clarify :-) ).

IMD also classifies whether the monsoon is normal or not based on this LPA. +/-10% of LPA is Normal. (see http://www.imd.gov.in/doc/termglossary.pdf. Lots of definitions there)

It would be interesting to have that 10% band on the rainfall tracker, and to highlight the drought years in Red or such colour.

On similar terms, in the erratic months graph, it would be great to have the respective normal bands for the months so that we can see how erratic the rainfall actually is.

Kind Regards
Mahroof

Hi Mahroof, 

Thanks for the information. I think you are absolutely right about the LTA, it would give more depth to the story. Will keep that in mind for all future visualisations. 

Thank you so much for your time and suggestions! I am really grateful to everyone who took time out to review my work.

Ravi-great visuals on rainfall. I just feel that there is too much data in one view....stories need simplicity.

Hello Ajay,

Thanks so much for the feedback. Really grateful you took time out to view the story and send this note. Hmm...point taken. I am working on another data visualisation and will try to keep it simpler. 

Thank you!
