\n\n**Objective:** To analyse the Global Superstore dataset and develop an interactive dashboard showcasing key business metrics, demonstrating proficiency in data connection, visualisation creation, and dashboard design within Tableau.\n\n**Key Activities \u0026 Skills Demonstrated:**\n\n* **Data Connection \u0026 Preparation:** Connected to the `global_superstore_2016` dataset; Verified and adjusted **`Data Types`** as needed.\n* **Core Visualisations:**\n    * **`Bar Chart`**: Created 'Sales by Region', **`Sorted`** regions by total sales (descending), and implemented a **`Filter`** for `Year`. ([View Bar Chart](https://public.tableau.com/views/20250311GlobalSuperstoreDashboard/SalesbyRegion?:language=en-GB\u0026:sid=\u0026:redirect=auth\u0026:display_count=n\u0026:origin=viz_share_link))\n    * **`Scatter Plot`**: Developed 'Profit Margin by Category', plotting `Profit` vs. `Sales`, using **`Colour Encoding`** to distinguish `Product Category`. ([View Scatter Plot](https://public.tableau.com/views/20250311GlobalSuperstoreDashboard/ProfitMarginbyCategory?:language=en-GB\u0026:sid=\u0026:redirect=auth\u0026:display_count=n\u0026:origin=viz_share_link))\n    * **`Line Chart`**: Built 'Shipping Cost Analysis', showing `Average Shipping Cost` over `Time` (Order Date), with **`Filters`** for `Ship Mode`. ([View Line Chart](https://public.tableau.com/views/20250311GlobalSuperstoreDashboard/ShippingCostAnalysis?:language=en-GB\u0026:sid=\u0026:redirect=auth\u0026:display_count=n\u0026:origin=viz_share_link))\n    * **`Pie Chart`**: Designed 'Order Priority Breakdown', displaying the distribution using a **`Table Calculation`** (`Percentage of Total`), with **`Filters`** for `Segment` and `Region`. ([View Pie Chart](https://public.tableau.com/views/20250311GlobalSuperstoreDashboard/OrderPriorityBreakdown?:language=en-GB\u0026:sid=\u0026:redirect=auth\u0026:display_count=n\u0026:origin=viz_share_link))\n* **Calculated Fields \u0026 Analytics:** Implicitly used aggregate functions (e.g., **`SUM`**, **`AVG`**) for visualisations; Applied **`Table Calculations`** (`Percent of Total`).\n* **Dashboard Design \u0026 Interactivity:** Combined the four worksheets into a single **`Dashboard`**; Configured **`Filter Actions`** to link filters across visuals, ensuring a cohesive and user-friendly experience.\n* **Formatting \u0026 Presentation:** Applied consistent **`Formatting`**, clear titles, and legends for a visually appealing and interpretable dashboard.\n\n---\n\n### Summary of Key Tableau Skills Demonstrated:\n\n* **Data Handling:** Connecting to data sources, Data Type management.\n* **Visualisation:** Creating various chart types (`Bar`, `Scatter`, `Line`, `Pie`), Sorting, Colour Encoding.\n* **Analytics:** Aggregate functions, Table Calculations (`Percent of Total`).\n* **Interactivity:** `Filters`, `Filter Actions`.\n* **Dashboarding:** Combining worksheets, Layout design, Formatting.\n\n\n## 📊 Example Output\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cimg src=\"image/Sales%20by%20Region.png\" width=\"500\" height=\"700\"/\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg src=\"image/Profit%20Margin%20by%20Category.png\" width=\"500\" height=\"700\"/\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cimg src=\"image/Shipping%20Cost%20Analysis.png\" width=\"500\"/\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg src=\"image/Order%20Priority%20Breakdown.png\" width=\"500\"/\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003ctd colspan=\"2\" align=\"center\"\u003e\n      \u003cimg src=\"image/global_superstore_dashboard.png\" width=\"1000\"/\u003e\n    \u003c/td\u003e\n  \u003c/tr\u003e\n\u003c/table\u003e\n\n\n\n### 🧑‍💻 Created by [tunjis](https://github.com/tunjis) \n\n-------------\n\n* 🌍  Based in \u003ca href=\"https://maps.app.goo.gl/hMxhRX5ptQAAkL7NA/\" target=\"_blank\"\u003e**London**\u003c/a\u003e\n* 🖥️  See my portfolio at [Data’s the new oil.
