A chart has many types and used by people all over the world. Therefore, the names of the charts also differ in each region. If the charts that we know are generally only a few (because it has become a standard in the international), in fact for every field of work or education, it is possible to have a chart that is not yet known by many people. So it cannot be ascertained how many of all chart types exist in the world.
On some charts, lines become an important part of it. Charts that don't have lines will need some adjustments to replace the function of lines. Lines on a chart are useful as a barrier or separator of some data that is presented using the chart. The number of lines on the chart also varies depending on the needs of the chart itself. If the data presented does not require many lines, that’s fine. Because the function of the chart itself is to make it easier for users to present data. If a chart using lines can help complete a good presentation of data, you can continue to use it to make your activities more efficient.
A printable blank chart can be found not only on the internet. If usually the internet always provides everything you need, now applications like Word, Excel, and PowerPoint can provide it for you.

Not all charts consist of lines, we think we agreed on the above. But if what is meant is a blank chart, is it possible to use it without lines. What is meant by blank charts without lines is that your paper does not contain anything related to the chart. There is no comparison, there are no lines for making allowances, and so on. You might have data to present, but if what you mean is to use blank charts without lines, maybe you should try making it yourself.
