encode_point_color
Set node color encoding in a graph using a specified column, with options for categorical mapping, default colors, or continuous gradients via Graphistry MCP.
Instructions
Set node color encoding for a graph using Graphistry's encode_point_color API.
Args:
graph_id (str): The ID of the graph to modify (from visualize_graph).
column (str): The node column to use for color encoding (e.g., 'type', 'score').
categorical_mapping (dict, optional): Map of category values to color codes. Example: {'mac': '#F99', 'macbook': '#99F'}. If not provided, Graphistry will auto-assign colors.
default_mapping (str, optional): Color code to use for values not in categorical_mapping. Example: 'silver'.
as_continuous (bool, optional): If True, treat the column as continuous and use a gradient palette. Example: True for numeric columns like 'score'.
Returns:
dict: { 'graph_id': ..., 'url': ... } with the updated visualization URL.
Example:
encode_point_color(graph_id, column='type', categorical_mapping={'mac': '#F99', 'macbook': '#99F'}, default_mapping='silver')
