Study changes to the Constitution of India within minutes — v2
Previously, pykih published with The Hindu in 2015. This visual itself received ~100 thousand visits in 2015 itself. But we kept receiving feedback from law and political science students and UPSC aspirants that while the visual itself was very useful in studying… it could have been better if it actually showed the constitution in context of the visual. Simply put — “Can we read what changed then and there?” We study this with our friends at ThinkIndia and Advocate Vishesh Bansal.


Before starting this effort, we wanted to ascertain if there is a need for use case to further invest in this visual.

Is there an audience for this? We know from the prototype in 2015 that students find the visual very useful. So how many students or experts are there who study the constitution? 

Have others built similar apps?

  • There are 16 apps on Constitution of India in the iOS App Store. There are over 150 apps in the Android Playstore with over 400k downloads.

Data Collection
We collected data from and tagged each line of the constitution using an identifier which helps browser detect which amendment was the line added or removed. The data annotation is attached.


No specific analysis was done on top of the data.


Changes: The design was inspired from Microsoft Word’s track changes feature where additions are displayed in blue color and deletions are displayed as strikethrough.

Heatmap: From, we retained the heat map of articles to show how often has each article changed.

The Prime Ministers and amendments could be plotted on a timeline.

Finally, two versions of the constitution need to be shown next to each other for easy comparison.

The final visual design is —
