## 🔧 **SPECIFIC FIXES MADE**

### **1. Node ID Handling** ✅
- **Before**: Examples used string node IDs like `g.add_node("alice")`
- **After**: All examples use numeric IDs: `alice = g.add_node(name="Alice")`
- **Impact**: All node operations now work correctly

### **2. API Method Accuracy** ✅  
- **Before**: Documented non-existent methods like `g.get_node()`, `g.update_node()`
- **After**: Replaced with working methods like `g.nodes[alice]`, `g.set_node_attribute()`
- **Impact**: No more broken method references

### **3. Filtering Syntax** ✅
- **Before**: Wrong syntax like `g.nodes.filter("age < 30")`
- **After**: Correct syntax: `g.filter_nodes(gr.NodeFilter.attribute_filter(...))`
- **Impact**: All filtering examples work

### **4. Analytics Module** ✅
- **Before**: Referenced non-existent `g.centrality.*`, `g.communities.*`
- **After**: Focus on available `g.analytics.*` methods
- **Impact**: Realistic expectations, no false promises

### **5. Table Operations** ✅
- **Before**: Non-existent methods like `table.mean('age')`
- **After**: Working patterns like `table['age'].mean()`
- **Impact**: All statistical operations work

### **6. Storage Views** ✅
- **Before**: Overly ambitious feature claims
- **After**: Accurate representation of current table/array/matrix capabilities
- **Impact**: Users can actually do what's documented
