Visualization

Available Tool

create_visualization: Create a chart specification for frontend rendering.

Parameters (MUST match exactly)

Parameter	Type	Required	Description
`chart_type`	str	Yes	`"bar"` , `"line"` , or `"pie"`
`data`	list[dict]	Yes	Array of data objects — see formats below
`title`	str	No	Chart title
`x_label`	str	No	X-axis label (bar/line only)
`y_label`	str	No	Y-axis label (bar/line only)

Data Formats (CRITICAL — use exact field names)

Bar / Line charts — each object MUST have

"x"

and

"y"

keys:

json

[{"x": "Jan", "y": 100}, {"x": "Feb", "y": 150}, {"x": "Mar", "y": 120}]

Pie charts — each object MUST have

"segment"

and

"value"

keys:

json

[{"segment": "Category A", "value": 30}, {"segment": "Category B", "value": 70}]

Optional: add

"color": "hsl(210, 100%, 50%)"

to any data point for custom color.

Example tool_input

Bar chart:

json

{
  "chart_type": "bar",
  "data": [{"x": "Q1", "y": 250}, {"x": "Q2", "y": 310}, {"x": "Q3", "y": 280}],
  "title": "Quarterly Revenue",
  "x_label": "Quarter",
  "y_label": "Revenue ($K)"
}

Pie chart:

json

{
  "chart_type": "pie",
  "data": [{"segment": "Mobile", "value": 60}, {"segment": "Desktop", "value": 35}, {"segment": "Tablet", "value": 5}],
  "title": "Traffic by Device"
}

Common Mistakes to Avoid

Do NOT use
```
{"labels": [...], "values": [...]}
```
format — data MUST be a list of dicts.
Bar/line data MUST use
```
"x"
```
and
```
"y"
```
keys, NOT
```
"label"
```
or
```
"name"
```
.
