symbol sum
lineWidth number — (height * 0.88 / (25 * height + 15))
sides number — number of sides that make up serif curve (5)
draw dynamic | static — 'static' updates vertices on resize, 'static' only changes scale transform (dynamic)
staticHeight number | first — used when draw=static. number sets height of static symbol - 'first' calculates and sets height based on first use ('first')

Example

// Define in element
figure.add({
  make: 'equation',
  elements: {
    sigma: { symbol: 'sum' },
  },
  forms: {
    form1: { sumOf: ['sigma', 'a', 'a = 0', 'n'] },
  },
});

Example

// Define inline simple one use
figure.add({
  make: 'equation',
  forms: {
    form1: { sumOf: ['sum', 'a', 'a = 0', 'n'] },
  },
});

Example

// Define inline with reuse
const eqn = figure.add({
  make: 'equation',
  forms: {
    form1: { sumOf: ['s1_sum', 'a', 'a = 0', 'n'] },
    form2: { sumOf: ['s1', 'a', 'a = 0', 'm'] },
  },
});
eqn.animations.new()
  .goToForm({ delay: 1, target: 'form2', animate: 'move' })
  .start();

Example

// Define inline with customization
figure.add({
  make: 'equation',
  forms: {
    form1: { sumOf: [{ sum: { lineWidth: 0.01 } }, 'a', 'a = 0', 'n'] },
  },
});
