KPI Dashboard using Tableau Superstore Data

Build a Superstore KPI dashboard with Royal Blue Analytics branding (#3B5998 primary blue, #1a365d navy). Include 5 KPI cards with sparklines showing Sales, Profit, Quantity, Avg Discount, and Profit Ratio with period-over-period comparison.

Add a Sales per Customer gauge chart (semicircle speedometer with gradient fill and target marker), a Regional Sales stacked area chart by West/East/Central/South, and a circular Voronoi treemap for state-wise sales.

Add an Order Distribution section with horizontal bars for Segment and Ship Mode, plus a chord diagram connecting segments to ship modes.

Add a Customer Segmentation radar chart with Current Year vs Prior Year comparison (Champions, Loyal, New, Needs Attention, Lost, At Risk) and RFM score sliders with wavy line indicators.

Add Sub-Category Analysis with a KPI card showing Appliances metrics (Sales, Profit, Orders, Customers stacked vertically with area chart trend) and a multi-line chart showing all sub-categories as light blue background lines with Appliances highlighted in primary blue.

Add a month filter dropdown (Jan 2023 - Dec 2026) that updates all charts dynamically, and include the Royal Blue Analytics logo in the header.
