Transaction amount trends over time (credit card fraud)

Visualized how transaction amounts evolved over time to spot patterns that may signal periods of higher fraud risk.

Details / full description:

Plotted transaction amounts over time for both fraudulent and legitimate transactions.

Looked for spikes, clusters, and unusual periods in the time series.

Used this view to discuss how monitoring transaction streams can help flag emerging fraud activity earlier.

Demonstrated how simple visualizations support analysts and data scientists in designing better alerts.

Clean structure and good use of filters for attendance tracking! Adding a department-wise summary tab on top would make it even easier for managers to spot patterns quickly. Did you build this for a real client or as a portfolio sample?"

Inventory and sales data side by side is a smart setup — makes stock decisions much faster. A reorder alert column flagging items below reorder level would add real operational value here. Is this a sample or a live client project?
