What problem does this feature solve?

1. zero is a very special value for continuous scale
2. a scale may need to combine domains from different data sources

What does the proposed API look like?

linearScale.nice(10, { zero: true,  });

linearScale.combineDomain([], true);

Steps to Reproduce

scale.domain([100, 100]);

Current Behavior

Expected Behavior

scale.tick() // return [100]

What problem does this feature solve?

complementary unit tests

What does the proposed API look like?

no new api

1. It's better to use color utils in vutils
2. math-utils also has some utils, such as clamp area duplicated with vutils

What problem does this feature solve?

support frequently used data format:

• 2d-array:

const data = [
    ['product', '2015', '2016', '2017'],  
    ['Matcha Latte', 43.3, 85.8, 93.7],  
    ['Milk Tea', 83.1, 73.4, 55.1],  
    ['Cheese Cocoa', 86.4, 65.2, 82.5],  
    ['Walnut Brownie', 72.4, 53.9, 39.1]   
] 

• Column based key-value format

const data = [
   'product': ['Matcha Latte', 'Milk Tea', 'Cheese Cocoa', 'Walnut Brownie'],
    'count': [823, 235, 1042, 988],
    'score': [95.8, 81.4, 91.2, 76.9]
] 

• Row based key-value

const data = [
