The Scatter plot is the chart that can be used to show the relationship between two numeric variables.

Here's why:

1. Scatter Plot: A scatter plot is a diagram where each value in the data set is represented by a dot. The position of a dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.

2. Bar Chart: A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart. But it doesn't show the relationship between two numeric variables.

3. Histogram: A histogram is an approximate representation of the distribution of numerical data. It was first introduced by Karl Pearson. To construct a histogram, the first step is to "bin" the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval. But it doesn't show the relationship between two numeric variables.

4. Line Chart: A line chart or line plot or line graph or curve chart is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically. But it doesn't show the relationship between two numeric variables.
