+dashboard for analyzing CVE exposure and robustness across robots models (Go1, Go2, H1, B1, B2, Z1).
 
 ## Features
 
-- 📊 **Dashboard** — KPI cards, severity donut, timeline bar chart, attack vector breakdown, CVEs per model
+- 📊 **Dashboard** — KPI cards, severity donut, timeline bar chart,CVEs per model
 - 🔍 **CVE Explorer** — searchable, filterable, sortable table with expandable CVE detail rows
 - ⚔️ **Model Comparison** — robustness score bars, radar chart per attack vector, avg/max CVSS overlay
-- 📂 **Load Data** — drag & drop support for **JSON, JSONL, CSV, Parquet** — merge or replace existing dataset
+  
+- 📂 **Load Data** tab lets you replace or merge the built-in dataset with your own CVE data, without editing any code.
+- ### Supported Formats
+
+| Format | Extension | Notes |
+| :--- | :--- | :--- |
+| **JSON** | `.json` | Array of objects, or object with `data` / `cves` key |
+| **JSONL** | `.jsonl` | One JSON object per line (newline-delimited) |
+| **CSV** | `.csv` | First row must be the header |
+| **Parquet** | `.parquet` | Read via `hyparquet` (requires CDN access) |
+
+### How to Use
+
+1. Go to the **📂 Load** tab.
+2. **Drag & drop** your file onto the dashed area, or click **"Browse Files"**.
+3. The dashboard shows a **preview** of the first 3 rows and the total record count.
+4. Choose one of:
+   - **⊕ Merge with existing** → append new CVEs to the current dataset.
+   - **⟳ Replace all data** → replace the entire dataset with the uploaded file.
+5. The dashboard updates automatically and switches back to the **Dashboard** tab.
