The honourable Supreme Court of India had ordered the State Bank of India (SBI) to provide all the details of electoral bonds to the Election Commission of India (ECI), who was then required to make it public. After initial hesitation, SBI finally provided all the details and ECI has published those details on their website. Out of curiosity, I downloaded the data and visualized it. This post is just a part of that visualization.

Nuances of $\LaTeX$ typesetting - d for derivative
Nov 09, 2022
If you often use $\LaTeX$ for typesetting math then you probably have come across the issue of typesetting d of infinitesimal small quantity dx. As per the standards, the d should be typed upright. But if you write dx in $\LaTeX$ math mode as $dx$, it will result in tilted d. In this article, we will explore a few ways of typesetting the d correctly in $\LaTeX$ math environment.

Oct 01, 2022
Plots library in julia is very powerful for plotting and I have rarely needed any other plotting library. However its documentation seems lacking in explaining its features, especially when you want to plot contours.

Data Lets consider a grid as shown in figure below. Each dot on the grid is a point with (x, y) coordinate pair and has an associated value of elevation of the point from ground level (z).

Method of weighted residuals
Oct 01, 2022
In Finite Element Method, the discussion often begins with something called as statement of weighted residuals. So let us explore what it means to me.
Some background Let us say we have a differential equation given by \eqref{eq:gde} with boundary condition as $y = 0$ at $x = 0$ and let us restrict ourselves to the domain $x \in [0, 1]$. \begin{equation} \dfrac{\mathrm{d}y}{\mathrm{d}x} = 3 x^{2} \label{eq:gde} \end{equation}
