Paths and shapes

Download notebookView on GitHubRun when the site was built.

Beyond simple node-to-node connections, tikzfigure lets you draw arbitrary paths from lists of (x, y) coordinates.

• drawing open and closed coordinate paths
• filldraw for filled closed shapes
• rounded corners
• per-segment styling with segment_options
• node paths and .center anchors for correct fills
• custom shapes (heart, star)
• parametric curves with NumPy (spiral, sun)
• fill for stroke-free fills and even-odd rule
• clip for clipping regions
• path for invisible named paths and mid-path labels

from tikzfigure import TikzFigure, arrows, styles, units

Open and closed coordinate paths

Pass a list of [x, y] pairs (or (x, y) tuples) to fig.draw(). Set cycle=True to close the path back to the starting point.

fig = TikzFigure()

# Open path - a zigzag
zigzag = [[0, 0], [1, 1], [2, 0], [3, 1], [4, 0]]
fig.draw(zigzag, line_width=2, color="blue")

# Closed path - a triangle
triangle = [[6, 0], [8, 0], [7, 1.5]]
fig.draw(
    triangle,
    cycle=True,
    line_width=2,
    color="red",
)

fig.show()

Filled shapes with filldraw

fig.filldraw() is shorthand for a closed path that is both drawn (outline) and filled. You can also use fig.draw(..., fill="color") for the same effect.

fig = TikzFigure()

# Pentagon via filldraw
angles = np.linspace(np.pi / 2, np.pi / 2 + 2 * np.pi, 6)[:-1]
pentagon = list(
    zip(
        np.cos(angles) * 2 + 2,
        np.sin(angles) * 2 + 2,
    ),
)
fig.filldraw(
    pentagon,
    cycle=True,
    line_width=2,
    color="purple",
    fill="purple!20",
)

# Same via draw(..., fill=...)
hexagon_angles = np.linspace(0, 2 * np.pi, 7)[:-1]
hexagon = list(
    zip(
        np.cos(hexagon_angles) * 2 + 7,
        np.sin(hexagon_angles) * 2 + 2,
    ),
)
fig.draw(
    hexagon,
    cycle=True,
    line_width=2,
    color="teal",
    fill="teal!20",
)

fig = TikzFigure()

# Same square, with increasing corner radius

Per-segment styling

segment_options accepts a list of per-connector option dicts, one for each to step in the path. Each dict uses keyword-style TikZ options (underscores become spaces) plus an optional "options" key for flag-style items like styles.dashed or arrows.forward.

Here four segments are given different colors and styles in a single draw call:

fig = TikzFigure()

waypoints = [[0, 0], [2, 2], [4, 0], [6, 2], [8, 0]]

fig.draw(
    waypoints,
    line_width=2,
    segment_options=[
        {"color": "red"},
        {"color": "blue", "options": [styles.dashed], "line_width": 1.5},
        {"color": "green!60!black", "line_width": 3},
        {"color": "purple", "options": [styles.dotted], "line_width": 2},
    ],
)

Per-segment bending works the same way. Here three nodes are connected with arrows where each segment curves in a different direction:

fig = TikzFigure()

specs = [("src", 0, 1, "teal"), ("mid", 4, 3, "orange"), ("dst", 8, 1, "purple")]
for label, x, y, color in specs:
    fig.node(
        (x, y),
        label=label,
        shape="circle",
        fill=f"{color}!25",
        draw=f"{color}!70",
        minimum_size=1.0 * units.cm,
        content=label.upper(),
    )

fig.draw(
    ["src.center", "mid.center", "dst.center"],
    arrows=arrows.forward,
    options=[styles.thick],
    segment_options=[
        {"bend_left": 30},  # src → mid curves upward-left
        {"bend_right": 25},  # mid → dst curves downward-right

Fluent node chaining

If you’re connecting named nodes, .to(...) is a concise alternative to building segment_options by hand. Options passed to .to(...) affect only that connector.

fig = TikzFigure()

A = fig.node(
    (0, 1),
    label="A",
    shape="circle",
    fill="teal!25",
    draw="teal!70",
    minimum_size=1.0 * units.cm,
    content="A",
)
B = fig.node(
    (4, 3),
    label="B",
    shape="circle",
    fill="orange!25",
    draw="orange!70",
    minimum_size="1cm",
    content="B",
)
C = fig.node(
    (8, 1),
    label="C",
    shape="circle",
    fill="purple!25",
    draw="purple!70",
    minimum_size="1cm",
    content="C",
)

fig.draw(
    A.to(B).to(C, options=styles.bend_left()),
    arrows=arrows.forward,
    options=[styles.thick],

Arc segments fit into the same fluent API. Unlike .to(...), .arc(...) does not consume another waypoint — it appends a TikZ arc[...] operation at the current point, and you can keep chaining afterward:

fig = TikzFigure()

A = fig.node(
    (0, 0),
    label="A",
    shape="circle",
    fill="teal!25",
    draw="teal!70",
    minimum_size="1cm",
    content="A",
)
B = fig.node(
    (4, 0),
    label="B",
    shape="circle",
    fill="orange!25",
    draw="orange!70",
    minimum_size="1cm",
    content="B",
)
C = fig.node(
    (7, 1.5),
    label="C",
    shape="circle",
    fill="purple!25",
    draw="purple!70",
    minimum_size="1cm",
    content="C",
)

fig.draw(
    A.to(B)
    .arc(start_angle=-90, end_angle=90, radius="1.5cm")
    .to(C, options=styles.bend_right()),

Use "out" and "in" keys for explicit departure and arrival angles (in degrees). This gives precise control over how each segment enters and leaves its endpoints — useful when bend_left/bend_right doesn’t give you the exact shape you need:

fig = TikzFigure()

for label, x, y, color in [
    ("A", 0, 2, "blue"),
    ("B", 5, 4, "orange"),

looseness scales how far the control handles extend, making the same bend either tighter (looseness < 1) or more exaggerated (looseness > 1). Here the two segments of the same symmetric path use opposite looseness values:

fig = TikzFigure()

for label, x, y in [("A", 0, 2), ("B", 5, 2), ("C", 10, 2)]:
    fig.node(

All segment options can be combined freely. Here each segment gets its own color, line style, and curve geometry in a single draw call:

Node paths and .center anchors

When you fill a closed path that goes through named nodes, TikZ routes to each node’s border by default. For circular nodes this means the filled area has indented corners — it doesn’t look like a triangle.

Appending .center to a node label in the path list routes the segment through the node’s geometric center instead. The path then bounds a proper filled polygon.

fig = TikzFigure()

node_specs = [
    ("top", 3, 4, "blue", r"$v_1$"),
    ("bl", 0, 0, "blue", r"$v_2$"),
    ("br", 6, 0, "blue", r"$v_3$"),
]
for label, x, y, color, text in node_specs:
    fig.node(
        (x, y),
        label=label,
        shape="circle",
        draw=f"{color}!60",
        fill="white",
        minimum_size="1.4cm",

You can mix anchors: only the nodes that need a specific anchor require the dot suffix. Any TikZ anchor string works — "north", "south east", "west", etc.

Parametric curves with NumPy

Any iterable of (x, y) pairs works as a path, so NumPy arrays plug in naturally for smooth parametric curves.

fig = TikzFigure()

# Spiral
N = 300
theta = np.linspace(0, 8 * np.pi, N)
r = np.linspace(0.1, 3, N)
spiral = list(
    zip(r * np.cos(theta) + 4, r * np.sin(theta) + 4),
)
fig.draw(spiral, line_width=2, color="teal")

fig.show()

Fill without stroke

fig.fill() fills a closed path without drawing any outline — the equivalent of \fill[...] in TikZ. Use it when you want pure flat colour with no border.

fig = TikzFigure()

# Three overlapping filled triangles — no outlines at all
triangles = [
    ([[1, 0], [4, 0], [2.5, 2.5]], "red!60"),
    ([[2, 0], [5, 0], [3.5, 2.5]], "blue!50"),
    ([[3, 0], [6, 0], [4.5, 2.5]], "green!60"),
]
for pts, color in triangles:
    fig.fill(
        pts,
        cycle=True,
        fill=color,
        fill_opacity=0.6,
    )

The even_odd_rule flag corrects the fill for self-intersecting paths. Without it, TikZ fills the interior using the non-zero winding rule, which fills the overlapping centre region twice — visually it looks like a solid shape. With even_odd_rule=True the centre hole is punched out correctly.

fig = TikzFigure()

angles = np.linspace(np.pi / 2, np.pi / 2 + 4 * np.pi, 6)[:-1]

Clip

fig.clip() installs a clipping path — all subsequent drawing is masked to the given boundary. Wrap the clip together with the clipped content inside a \begin{scope}...\end{scope} via fig.raw() so the clip doesn’t leak into the rest of the figure.

fig = TikzFigure()

# Draw a full circle for reference (unclipped)
fig.draw(
    list(
        zip(
            np.cos(np.linspace(0, 2 * np.pi, 60)) * 2 + 2,
            np.sin(np.linspace(0, 2 * np.pi, 60)) * 2 + 2,
        ),
    ),
    cycle=True,
    color="gray!40",
    line_width=1,
)

# Open a scope, clip to a rectangle, then draw a dense grid inside
fig.raw(r"\begin{scope}")
clip_rect = [[0.5, 0.5], [3.5, 0.5], [3.5, 3.5], [0.5, 3.5]]
fig.clip(clip_rect, cycle=True)

Invisible path

fig.path() traces a path without drawing or filling anything. It has two common uses:

Named paths — register a path under a name so the intersections TikZ library can compute where two paths cross.

Mid-path labels — place a text node at a specific position along an invisible connector using segment_options with a "node" key.

fig = TikzFigure()

for label, x, y, color in [
    ("A", 0, 0, "teal"),
